Carbon-Sulfur Reductive Elimination from Palladium(IV) Sulfinate Complexes

摘要

Palladium complexes are among the most versatile catalysts that are capable of constructing a variety of bonds.'1'21 Consequently, fundamental studies on palladium complexes have a great impact on the design and understanding of practical catalytic processes. Studies on reductive elimination to form C-X bonds (X = CF3, C, O, Cl, F) from Pd~(IV) complexes have recently been achieved. Despite the importance of sulfur-containing products, related mechanistic studies on C-S bond-forming reactions are rare. Herein we report the synthesis, characterization, and study of novel palladium(IV) sulfinate complexes. We describe the first direct observation of C-S bond-forming reductive elimination from Pd~(IV) complexes.
