Ni(ii)-N?NN? pincer complexes catalyzed dehydrogenation of primary alcohols to carboxylic acids and H2 accompanied by alcohol etherification

Acceptorless dehydrogenation of alcohols to carboxylic acid derivatives catalyzed by a transition metal complex is an important reaction in modern organic synthesis and catalysis, for which nickel complexes have rarely been developed. Herein we report three Ni(ii) complexes bearing pyridine-based N?NN? type pincer ligands, which catalyze the acceptorless dehydrogenation of primary alcohols to carboxylic acids under anhyrous conditions. The complex [NiCl2(L3)] 3 (L3 = 2,6-bis(diethylaminomethyl)pyridine) displays the best catalytic reactivity, catalyzing the primary alcohols to carboxylic acids and H2 in good yields (40-90%). Further investigation reveals that an unexpected alcohol etherification occurs, which gives the second oxygen atom for the formation of the carboxylic acid. Our results give a thread for the design of new nickel complexes without phosphine and N-heterocycle carbene ligands for the acceptorless oxidation of alcohols.

A bindschedler’s green-based arylamine: Its polycations with high-spin multiplicity

Intramolecular high-spin correlation in a series of the successively generated polycationic species of Bindschedler’s green-based arylamine, N,N,N?,N?,N?,N?-hexakis[4-(dimethylamino)phenyl]-1,3, 5-benzenetriamine (1), has been investigated by continuous wave (CW) and pulsed EPR spectroscopy. Cyclic voltammetry shows multiredox behavior of 1 that can be reversibly oxidized from monocation to hexacation. Depending on the quantity of the added oxidant, the characteristic EPR spectra are observed for polycations of 1 in frozen solution. Unequivocal determination of the spin state at each oxidation stage of 1 is given by a pulsed EPR technique, that is, electron spin transient nutation spectroscopy.

Oxidative addition chemistry of tetrathiocines: Synthesis, structures and properties of group 10 dithiolate complexes

Oxidative addition of the electron-rich tetra-methoxy-dibenzo-1,2,5,6- tetrathiocine [(MeO)2C6H2S2] 2 to zero-valent group 10 transition metal complexes in the presence of diphenylphosphinoethane (dppe) affords the corresponding dithiolate complexes, [(DMOBD)M(dppe)] (DMOBD = dimethoxybenzenedithiolato, (MeO) 2C6H2S22-; M = Ni, Pd, Pt) in high yield which were characterized by single crystal X-ray diffraction. Whereas the Pd and Pt complexes exhibit two quasi-reversible 1e- oxidation processes, the nickel species undergoes a quasi-reversible 1e – reduction.

Synthesis of O,N,O[sbnd]P multidentate ligands and the formation of early?late heterobimetallic complexes

A multidentate O,N,O[sbnd]P ligand 4 designed for early?late heterobimetallic (ELHB) complexes was synthesized. The ligand 4 has an O,N,O-tridentate ligand moiety and a triarylphosphine group. The O,N,O-moiety based on lutidine scaffold selectively coordinated to early transition metals such as titanium and niobium in the reaction with the corresponding metal alkoxides to form mononuclear complexes. Coordination of the triarylphosphine moiety to the niobium atom was negligible in the Nb-ONO[sbnd]P complex according to 31P NMR spectroscopy, whereas a part of the phosphorus atom coordinated to the titanium atom in the Ti-ONO[sbnd]P complex. Addition of [PdCl(pi-allyl)]2 or [RhCl(cod)]2 to the Nb-ONO[sbnd]P complex gave rise to the formation of ELHB complexes. Thus, the one-pot preparation of ELHB complexes was achieved by simple procedure.

Chiral monodentate trialkylphosphines based on the phospholane architecture

The development of efficient chiral monodentate phosphine ligands lags behind that of the bidentate congeners. This holds especially true for highly electron rich chiral phosphine analogues able to replace the ubiquitous tricyclohexylphosphine and tri-tert-butylphosphine in catalytic asymmetric transformations. We present a convenient and modular synthesis of a set of chiral monodentate ligands with different steric demands based on the popular phospholane scaffold. Their steric and electronic properties were determined by their corresponding nickel and palladium complexes. They represent good mimics of the popular tricyclohexylphosphine and tri-tert-butylphosphine ligands. Their potential was subsequently evaluated in palladium-catalyzed asymmetric C(sp3)-H functionalization leading to indolines.

Synthesis, characterization and theoretical and fluorescence emission microscopy studies of new Pd/Pt?cyclopropa[60]fullerene complexes: Application of Taguchi method for optimization of parameters in Suzuki?Miyaura reaction

The reactions of unsymmetric phosphorus ylides of the type [Ph2P(CH2)nPPh2?C(H)C(O)C6H4-p-CN] (n?=?1 (Y1); n?=?2 (Y2)) with C60 and M(dba)2 (M?=?Pd or Pt; dba?=?dibenzylideneacetone) are reported. Based on the various coordination modes of these ylides in complexation, the following new Pd/Pt?cyclopropa[60]fullerene complexes were obtained: P,C-coordinated [(eta2-C60)Pd(kappa2-Y1)] (1) and [(eta2-C60)Pt(kappa2-Y1)] (2) complexes and P-coordinated [(eta2-C60)Pd(Y2)2] (3) and [(eta2-C60)Pt(Y2)2] (4) complexes. These compounds were characterized using Fourier transform infrared, UV?visible and NMR (1H, 13C and 31P) spectroscopies and scanning electron microscopy. Furthermore, cytotoxicity studies showed that nanoparticles of these complexes can be used as non-toxic labels for cellular imaging application. Also energy decomposition analysis results revealed that the percentage contribution of DeltaEelec in total interaction energy is considerably larger than that of DeltaEorb. Thus, in all complexes the (eta2-C60)M?(Y1) bond is considerably more electrostatic in nature than the (eta2-C60)?M(Y1) bond. Finally, by application of the Taguchi method for optimization of parameters in Suzuki?Miyaura reaction, the catalytic activity of Pd complexes 1 and 3 was investigated in the cross-coupling reaction of various aryl chlorides with phenylboronic acid. According to analysis of variance results, solvent has the highest F value and it has high contribution percentage (36.75%) to the yield of Suzuki?Miyaura reaction.

Synthesis of Electron-Deficient Heteroaromatic 1,3-Substituted Cyclobutyls via Zinc Insertion/Negishi Coupling Sequence under Batch and Automated Flow Conditions

Synthesis of 1,3-substituted cyclobutyls enabled by zinc insertion into functionalized iodocyclobutyl derivatives followed by Negishi coupling with halo-heteroaromatics is reported. Two distinct sets of conditions were developed; the first involved a two-step batch protocol using activated Rieke zinc, and the second involved a multistep continuous flow process. Both methods showed complementarity and allowed for rapid access to these medicinally relevant motifs, the possibility of scaling up, and automation for library synthesis.
