Abstract

Abstract Thirteen different symmetric and asymmetric phosphinesulfonato palladium complexes ([{(X 1-Cl)-μ-M} n], M= Na, Li, 1= X (P^ O) PdMe) were prepared (see Figure 1). The solid-state structures of the corresponding pyridine or lutidine complexes were determined for (MeO) 2 1-py,(iPrO) 2 1-lut,(MeO, Me2) 1-lut,(MeO) 3 1-lut, CF3 1-lut, and Ph 1-lut. The reactivities of the catalysts X 1, obtained after chloride abstraction with AgBF 4, ...
