An improved protocol for the palladium-catalyzed cyanation of electron-rich aryl chlorides with potassium ferrocyanide [K4[Fe(CN)6]] is presented. Compared to previous procedures the substrate scope is significantly broadened.

An attempt was made to synthesize a series of non-cytotoxic low molecular weight meta-substituted aromatic ethers (2-4, 5-7) and some of their bioisosteres (14-16) and to evaluate their activity on the activation of human complement (classical pathway) and their intrinsic hemolytic activity. The in vitro assay results of the inhibition of complement-mediated hemolysis by these analogues indicate that the aldehydic meta substituted aromatic ethers show inhibitory potency, while carboxylic acid meta substituted aromatic ethers show hemolytic activity. Some of the bioisosteres exhibit both inhibitory as well as hemolytic property.

Developing environmentally friendly catalysts with high activity for the ammoxidation of aromatic aldehydes to aromatic nitriles is greatly important for this industrial transformation. Herein, natural vitamin B12 was used as a carbon source for the preparation of a cobalt- and nitrogen-doped catalyst precursor, which was pyrolyzed at different temperatures to obtain cobalt- and nitrogen-doped carbon (Co@NC-T) (T denotes pyrolysis temperature) catalysts. The Co@NC-800 exhibited excellent activity and selectivity in the ammoxidation of aromatic aldehydes with ammonium carbonate to aromatic nitriles compared to the Co@NC-700, Co@NC-600 and Co@NC-500 catalysts. The high catalytic performance of Co@NC-800 could be due to the presence of the low-density electron cloud of the highly dispersed Co species, which could interact with the benzene ring of benzaldehyde bearing p-π conjugate, thereby promoting the adsorption and activation of benzaldehyde. Consequently, the activated benzaldehyde reacted with amino groups that were decomposed from ammonium carbonate and subsequently underwent a dehydration process to form nitriles.

A Cu-catalyzed cross-coupling reaction between aryl bromides and 9-BBN-OMe to provide aryl methyl ethers under mild conditions is reported. The oxalamide ligand BHMPO plays a key role in the transformation. Various functional groups on bromobenzenes are well tolerated, providing the desired anisole products in moderate to high yields.
