A catalyst system comprising *CHCl3 and DPPF was proved to be efficient for the cyanation of aryl iodides and aryl triflates with KCN.The reactivities of aryl substrates decreased in the order ArI > ArOTf > ArBr.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C52H43Cl3O3Pd2, you can also check out more blogs about52522-40-4

TWIM peaks: A macrocycle containing 12 PdII terpyridyl centers was assembled using 4,4?-bipyridyl ligands and characterized by NMR and traveling wave ion mobility mass spectrometry (TWIM-MS). The macrocyclic architecture was also examined by tandem mass spectrometry and collisionally activated dissociation (CAD) experiments (see picture; C gray, N blue, Pd orange), and the resulting fragments were monitored by time-of-flight mass analysis.

An efficient one-pot, two-step procedure has been successfully applied for the synthesis of a series of 2-(5-phenylindol-3-yl)benzimidazoles. The first step was cyclocondensation-oxidation of 5-bromoindole-3-aldehydes with o-phenylenediamines in 1,4-dioxane, which was promoted by activated carbon and used atmospheric air as a “green” oxidant. The resulting 2-(5-bromoindol-3-yl)benzimidazoles in the pot were in situ coupled with postadded phenylboronic acids, and catalyzed with PdCl2(dppf) in 1,4-dioxane-H2O to afford the desired compounds with satisfactorily high yields. The relationship between the synthesized compounds’ absorption, and fluorescence spectra with molecular structures has been investigated with experimental data and theoretical calculations.

We report herein the first examples of a palladium-catalyzed enantioselective Cacchi reaction for the synthesis of indoles bearing a chiral C2-aryl axis. In the presence of a catalytic amount of Pd(OAc)2 and (R,R)-QuinoxP* ligand, reaction of N-aryl(alkyl)sulfonyl-2-alkynylanilides with arylboronic acids under oxygen atmosphere afforded enantioenriched 2,3-disubstituted indoles in high yields and enantioselectivity. The indole ring is constructed de novo in this process and a complexation-induced chirality transfer is proposed to account for the observed enantioselectivity.

Ethynyl-bridged porphyrin-corrole dyads and triads were synthesized by using Pd(0) mediated coupling reactions and their structures were characterized by NMR, FT-IR, UV/Vis and fluorescence techniques. Besides spectroscopic techniques, computational studies at B3LYP/6-311G(d,p) level of DFT were also used to elucidate the minimum energy geometries and the molecular orbital characteristics of the new dyads and triads. DFT calculations pointed out the presence of charge separated donor-acceptor property between macrocycles of dyads and triads, and the emission studies indicated an excited state interaction between macrocycles, and energy transfer from the porphyrin to the corrole unit.

Zinc methyl 20-substituted 31-demethyl-bacteriopheophorbides-d were prepared through palladium-catalyzed cross-coupling of chlorophyll-a derivatives. The synthetic zinc 31-hydroxy-131-oxo-chlorins possessing a(n) (un)substituted ethynyl or butadiynyl group at the 20-position were good models for bacteriochlorophylls-c/d found solely in chlorosomes, the main light-harvesting antennas of green photosynthetic bacteria. Similarly as in natural chlorosomes, the synthetic models self-aggregated in an aqueous Triton X-100 solution to form large oligomers with red-shifted and broadened electronic absorption bands. While a phenyl group directly connected with the chlorin pi-system at the 20-position disturbed the chlorosomal self-aggregation, the insertion of an ethynylene group between the two functional groups reduced the steric hindrance around the 20-position and was useful for the facile formation of the self-aggregates. A similar substitution effect was observed in the 20-ethynyl to butadiynyl moieties bearing a sterically bulky trimethylsilyl group at the terminal position.
