Abstract

Abstract Abstract The reactions of organotin compounds with organic halides and acid halides catalysed by palladium complexes without phosphine ligands have been carried out under very mild conditions. These reactions afford biaryls, tolans, styrenes, dienes, and unsymmetrical ketones having various substituents. The synthesis of organotin compounds may be realized through the reactions of organic halides with hexaaryldistannanes catalysed by palladium and nickel complexes. The palladium-catalysed carbonylation of organic halides in the presence of organotin compounds of the series Alk SnNu (Nu= R, MeO, PhS, Et N, SnAik ) has proved to be a convenient method for the synthesis of ketones, derivatives of aromatic acids and o:-diketones.
