(Salen-OH)Pd (1, salen-OHN,N′-bis(3,5-di-hydroxysalicylidene)- ethylenediamine) was prepared by a simple one step reaction and fully characterized by 1H and 13C NMR, IR spectroscopy, and X-ray crystallography. This palladium complex showed good activities as a catalyst in the Mizoroki-Heck-type reaction and the decarboxylative coupling reaction. In the Mizoroki-Heck type reaction, arylboronic acids and alkenes were reacted at 90°C for 3 h in the presence of 2.0 mol% of the palladium complex 1 and AgOAc to give the desired coupled product in good yields. In the decarboxylative coupling reactions, the desired coupled products were obtained in good yields when 0.5 mol% of the palladium complex was employed at room temperature.

The biological synthesis of metal nanoparticles from ions has recently emerged as a novel technique for an environmentally benign recovery of heavy metals. Bacteria are known to recover palladium(0) in the form of nanoparticles that are catalytically active. However, the extent of the reactions that can be catalysed by bio-recovered palladium has not been investigated. This study demonstrates that the Suzuki-Miyaura and Mizoroki-Heck reactions can be catalysed by bio-generated palladium nanoparticles formed on the surface of Gram-negative bacteria. The results suggest that the range of applications of this catalyst can be extended to the realm of carbon-carbon bond formation in synthetic organic chemistry.

α,β-Unsaturated aldimines were specifically oxidized to amides with Oxone in the presence of AlCl3 as a Lewis acid in CH2Cl2. No migration of aryl group occurred in the rearrangement reaction. Copyright Taylor & Francis Group, LLC.
Rhodium-catalyzed heck-type coupling of boronic acids with activated alkenes in an aqueous emulsion

Intermolecular couplings between arylboronic acids and activated alkenes catalyzed by a water-soluble tert-bulyl amphosrhodium complex were found to progress at room temperature and generated Heck-type products with high yields and excellent selectivity. Substitution on the alkene component encouraged the formation of products arising from a conjugate addition-protonation process. In the case of Heck product formation, it was necessary to add two equivalents of the alkene component whereby one equivalent is believed to act as a sacrificial hydride acceptor.
