Synthesis and reactivity of phosphanido bridged 1,1?-bis(diphenylphosphino)ferrocene complexes [(RF)2Pt(mu-PPh2)2M(dppf)] [M = Pt, Pd]

Hetero-trinuclear complexes of formula [(C6F5)2Pt(mu-PPh2)2M(dppf)] [dppf = 1,1?-bis(diphenylphosphino)ferrocene, M = Pt (1), M = Pd (2)] were prepared by coupling between cis-[(C6F5)2Pt(PPh2)2]Li2and cis-MCl2(dppf). Reaction of the Pt/Pt/Fe species 1 with [Ag(OClO3)(PPh3)] or I2resulted in the formation of the complexes [(C6F5)(PPh3)Pt(mu-PPh2)2Pt(dppf)] (3) and [(C6F5)(I)Pt(mu-PPh2)2Pt(dppf)] (4), respectively, in which one of the pentafluorophenyl ligands has been replaced by PPh3or I. Reaction of the Pt/Pd/Fe species 2 with Ag(ClO4) afforded the tetranuclear complex [(C6F5)2Pt(mu-PPh2)2Pd(dppf)Ag] (5) where the silver atom is bonded to Pd, to one of the bridging P and to one of the dppf P atoms. With [Ag(OClO3)(PPh3)], complex 5 is also formed, although mixed with [Ag(PPh3)2][ClO4]. A dynamic process in solution, in which the silver atom passes from one Pd?muPPh2bond to the other, has been observed at room temperature for complex 5. The crystal structures of 3, 4 and 5 are reported.

Tribromide ion immobilized on magnetic nanoparticles as an efficient catalyst for the rapid and chemoselective oxidation of sulfides to sulfoxides

Tris(tetraalkyl ammonium tribromide) immobilized on Fe3O4 magnetic nanoparticles (Br3-Fe3O4) is a stable, green, and magnetically recoverable source of bromine and used as an efficient nanocatalyst for the clean and rapid oxidation of sulfides to sulfoxides using hydrogen peroxide (H2O2), with short reaction times in good to high yields under solvent-free conditions. After completing reactions, the catalyst was easily separated using an external magnetic field from the reaction mixture and reused for several consecutive runs without significant loss of its catalytic efficiency. The nanomagnetically catalyst was characterized by FT-IR spectroscopy, TGA, VSM, XRD, TEM and SEM.

Synthesis and characterization of bis(4-amino-2-bromo-6-methoxy)azobenzene derivatives

Aminoazobenzene derivatives with four ortho substituents with respect to the N-N double bond are a relatively unexplored class of azo compounds that show promise for use as photoswitches in biology. Tetra-ortho-methoxy-substituted aminoazobenzene compounds in particular can form azonium ions under physiological conditions and exhibit red-light photoswitching. Here, we report the synthesis and characterization of two bis(4-amino-2-bromo-6-methoxy)azobenzene derivatives. These compounds form red-light-absorbing azonium ions, but only under very acidic conditions (pH < 1). While the low pKa makes the azonium form unsuitable, the neutral versions of these compounds undergo trans-to-cis photoisomerization with blue-green light and exhibit slow (tau1/2 ? 10 min) thermal reversion and so may find applications under physiological conditions.

New Iron(II) Spin-crossover Complexes with Heterocyclic Amine-derived Ligands and STEPS Experiments on Photogenerated Metastable High-spin States

Cationic complexes of the type 2+ and 2+ have been isolated as Cl-, ClO4-, or BF4- salts, where LNN and LNNN represent bidentate and tridentate nitrogen-donor ligands respectively.The bidentate ligands were 2-(2’pyridyl)benzimidazole (pybzim), 2-(2′-pyridyl)-N-methylbenzimidazole (mpybzim); 2-(2′-pyridyl)benzothiazole (pybzt), 2,2′-dipyridylamine (dpya), and the tridentates di(2-pyridylmethyl)amine (dpyma), 2,6-bis(benzimidazol-2′-yl)pyridine (bzimpy), 2,6-bis(N-methylbenzimidazol-2′-yl)pyridine (mbzimpy), and 2,6-bis(benzothiazol-2′-yl)pyridine (bztpy).Except for , all these FeN6 chromophores exhibit strong absorption in the 550 nm region, which is assigned as a metal-to-ligand charge-transfer transition.Between 4 and 320 K, the iron(II) is in the low-spin form in the majority of these compounds; high-spin exceptions are 2 and Cl2.Other complexes show evidence of the onset of a spin transition near 40 deg C, while the salt *CHCl3 is a well defined spin-crossover system.The low-spin complex 2 was excited by irradiation with visible light, and the generation and decay of resulting high-spin form was observed under cryogenic conditions.In solution, 2+ acts as a weak diprotic acid and also exhibits quintet ->/<- singlet spin crossover (DeltaHo = -42.7 kJmol-1, DeltaSo = -140.9 JK-1mol-1).The complexes are all electrochemically oxidizable to their iron(III) forms in non-aqueous solution, but the dpyma, bztpy, pybtz, and dpya chelates thus formed are unstable.The iron(III) complex – containing the doubly deprotonated ligand was obtained as its low-spin triethylammonium salt.The high-spin chloro complexes . , Fe(mbzimpy)Cl2, and the mixed-spin iron(II) complex salt were also isolated.

Peptide Ligation via the Suzuki-Miyaura Cross-Coupling Reaction

Chemoselective ligation of two 28-mer peptides has been accomplished using the Suzuki-Miyaura cross-coupling reaction at or near physiological temperature in an aqueous solution containing sodium dodecyl sulfate in 83% yield. The effects of Pd source, solvent, base, and temperature were investigated, and the optimized reaction conditions were studied for compatibility with naturally present and artificially introduced functional groups in peptides including S-protected thiol and azide. The peptide conjugations were carried out in high yield (90%) with their functional groups intact. This method also allowed for facile introduction of an affinity tag or fluorescent probe into 20-mer peptides in >80% yield. These results suggest that the Suzuki-Miyaura cross-coupling is useful for multiple conjugations of peptides in conjunction with conventional conjugation reactions performed in sequence.

Bidentate ferrocenylphosphines and their palladium(II)dichloride complexes – X-ray structural and NMR spectroscopic investigations and first results of their characteristics in the Pd-catalysed cooligomerisation of 1,3-butadiene with CO2

The chiral 1,1?-bis(di(+)-menthylphosphino)ferrocene (dmenpf, 1b) and achiral 1,1?-bis(diisopropylphosphino)ferrocene (disoppf, 1a) were prepared from the corresponding tertiary chlorophosphines 2b and 2a and the dilithiated ferrocene-TMEDA complex as analytically pure crystals. The synclinic eclipsed conformation of the Cp rings and the Cp(1)-Fe-Cp(1)? angle in 1b was determined to be 175.0(2) by X-ray structure analysis. With H2[PdCl4] 1a forms the bimetallic complex (disoppf)PdCl2 (3a). In contrast to the structure of the free ligand disoppf (1a), the X-ray structure of 3a and the NMR spectra in solution as well as in the solid state show that the P atoms are chemically and magnetically equivalent. The conformation of the Cp rings converts from an eclipsed to a staggered conformation. The ferrocene-based ligands show significant activity in the Pd-catalysed cooligomerisation of 1,3-butadiene with CO2

Arylation of Adamantanamines: X. Palladium- and Copper-Catalyzed Heteroarylation of Adamantane-Containing Amines with Bromopyridines

The catalytic efficiencies of palladium(0) and copper(I) complexes in the amination of 2-bromopyridine and its fluorine-containing derivatives with (1-adamantyl)methanamine and 2-(1-adamantyloxy)ethanamine were compared. Both types of catalytic systems were shown to be applicable for the preparation of the corresponding N-pyridyl derivatives from 3- and 5-fluoro- and 4-, 5-, and 6-trifluoromethyl-2-bromopyridines. DavePhos was found to be the most efficient ligand in the Pd(0)-catalyzed reactions; however, the reactions with 2-bromo-4-(trifluoromethyl)pyridine and 2-bromo-5-(trifluoromethyl)pyridine were accompanied by formation of a considerable amount of the diarylation product. The diarylation process was significantly suppressed in the presence of copper(I) complexes.

Organocatalytic diboration involving “reductive addition” of a boron-boron-bond to 4,4?-bipyridine

A 4,4?-bipyridine-based catalyst system for diboration of pyrazine derivatives was established. The catalyst cycle consists of the following two steps: (1) reductive addition of the boron-boron bond of bis(pinacolato)diboron to 4,4?-bipyridine to form N,N?-diboryl-4,4?-bipyridinylidene and (2) oxidative boryl transfer from the intermediate to pyrazine to give N,N?-diboryl-1,4-dihydropyrazine with regeneration of 4,4?-bipyridine.
