palladium(II) and platinum(II) complexes with the mono- and bis-chelate ligands bis[o-(methylthio)phenyl]phosphine and tris[o-(methylthio)phenyl]phosphine have been prepared and characterised. Despite the potential tridenticity of the first ligand it acts as a P/S monochelate to form square-planar complexes of type [MPPh(C6H4SMe-o)2}X2](M = Pd, X = Cl, Br or I; M = Pt, X = Cl).

Asymmetrically substituted tertiary phosphines and quaternaryphosphonium salts are used extensively in applications throughout industry and academia. Despite their significance, classical methods to synthesize such compounds often demand either harsh reaction conditions, prefunctionalization of starting materials, highly sensitive organometallic reagents, or expensive transition‐metal catalysts.

PdII complexes with PPh(o-C6H4SMe)2 acting as a pincerligand in an S,S′,P- or S,P-coordination mode have been synthesized. The complexes include [PdCl2PPh(o-C6H4SMe)2}] (1), [Pd(Me)ClPPh(o-C6H4SMe)2}] (2), and [Pd(X)PPh(o-C6H4SMe)2}]A [A = CF3SO3, X = Cl (3); A = CF3SO3, Me (4); A = PF6, X = Me (5)]. Insertion of CO into the Pd–Me bond of these complexes leads to [Pd(COMe)ClPPh(o-C6H4SMe)2}] (6)
PdII 复合物与 PPh(o-C6H4SMe)2 作为钳形配体以 S,S',P- 或 S,P- 配位模式合成。配合物包括 [PdCl2PPh(o-C6H4SMe)2}] (1)、[Pd(Me)ClPPh(o-C6H4SMe)2}] (2) 和 [Pd(X)PPh(o- C6H4SMe)2}]A [A = CF3SO3, X = Cl (3); A = CF3SO3,我(4);A = PF6,X = Me (5)]。将 CO 插入这些配合物的 Pd-Me 键中导致 [Pd(COMe)ClPPh(o-C6H4SMe)2}] (6) 和 [Pd(COMe)PPh(o-C6H4SMe)2}]A [A = CF3SO3 (7); A = PF6 (8)]。其中一些配合物是良好的 Mizoroki-Heck 催化剂(用于碘苯与丙烯酸甲酯或苯乙烯之间的反应)。发现活性最强的催化剂是 [Pd(
