New Pd( ii ) complexes of sulfur ylides; synthesis, X-ray characterization, a theoretical study and catalytic activity toward the Mizoroki–Heck reaction

The reaction of sulfur ylides SMe 2 C(H)C(O)R (R = 4-nitrophenyl, phenyl, and 3-nitrophenyl) with [PdCl 2 (cod)] gives the new Pd( ii ) complexes of type cis - and trans -[PdCl 2 (SMe 2 C(H)C(O)R) 2 ] (R = phenyl ( 1 ), 3-nitrophenyl ( 2 ), and 4-nitrophenyl ( 3 )).
