Popis:	The catalytic activity of palladium chalcogenolate complexes, [PdCl(ECH 2 CH 2 NMe 2 )] 3 (E = S or Se), [PdCl(ECH 2 CH 2 CH 2 NMe 2 )] 2 and [PdCl(SeCH 2 CH 2 NMe 2 )(PPh 3 )] has been investigated in carbonylative Suzuki coupling reactions. The phosphine complex has also been used as a catalyst in C C cross coupling reactions involving an aryl halide and either triaryl bismuth or aryl boronic acid (Suzuki coupling). The catalytic system was also explored for other carbonylation reactions including carbonylative Sonogashira coupling and amino carbonylation reaction. The phosphine complex showed better activity in carbonylative Suzuki coupling reactions than dimeric and trimeric complexes. All the complexes showed comparable activity in Suzuki coupling reactions.
