Abstract

Four new palladium complexes of mixed phosphine and N-containing heterocyclic thiolates are synthesized and characterized.  The reaction of cis-(PPh3)2PdCl2 with N-containing heterocyclic thiols (Nhet-SH) occurred in the presence of a base and produced trans-(PPh3)2Pd(κS-S-Nhet)2 (S-Nhet = SC4H5N2 (1), S2C3H3N2 (2)). However, the correspond­ing reaction of (dppf)PdCl2 with the same thiols produced cis-(dppf)Pd(κS-SN-het)2 (dppf = 1,1'-bis(diphenylphosphino)ferrocene; SC4H5N2 (3),  S2C3H3N2 (4)). Complexes 14 are characterized by IR, UV-Vis, 1H-NMR,13C-NMR, and 31P-NMR spectroscopy and elemental analysis.
