The one-pot, palladium-catalyzed, three-component coupling of aryl bromides, internal alkynes, and environmentally friendly K4[Fe(CN)6] provides an efficient and direct method for the preparation of beta-arylalkenylnitriles.

Aryl nitriles were prepared through Cu(NO3)2·3H2O-mediated cyanation of aryl iodides and bromides using DMF as a single surrogate of cyanide. Moreover, this protocol could be scalable and practiced with benign operation.

The cross-coupling reaction of diarylamines with aryl bromides/iodides can be effected by the Ni(ii)-(sigma-aryl) complex/PPh(3)/NaH system, and a preliminary investigation was conducted into the mechanism of this reaction.

Abstract An efficient cycloaddition reaction of trifluoroacetohydrazonoyl bromides with nitroolefins was developed, which regioselectively produced 3‐trifluoromethyl‐4‐substituted pyrazoles. The has the advantages mild conditions, good tolerance functional groups and simple operation.

In the vast majority of atom transfer radical polymerizations, alkyl bromides or chlorides are commonly employed as initiators. Herein, iodides demonstrated ATRP

This study presents a comprehensive periodic slab DFT investigation into structures, electronic properties and thermodynamic stability of all plausible terminations of CuBr and CuBr2 surfaces. We first estimate lattice constants, formation and cohesive energies for the two bulk copper bromides before proceeding to analyse geometrical and electronic features of CuBr and CuBr2 configurations.
