Abstract

Abstract Pincer thioamide Pd II complex 2 was prepared, and its reaction with cyclohexylzinc chloride yielded novel pincer thioimide Pd II complex 3 besides Pd 0 species. The structures of complexes 2 and 3 were confirmed by X-ray analysis. Both complexes are efficient catalysts for Negishi couplings involving primary and secondary alkyl zinc reagents bearing β-hydrogen atoms. At a concentration of 0.1–0.5 mol% both catalysts readily promoted ...
