Coordination Complexes of the Dimethylthiophosphonium Cation and Ligand Exchange

The quantitative exchange of a 4-(dimethylamino)pyridine ligand on the dimethylthiophosphonium cation by Me3P demonstrates the coordinative nature of the N−P and P−P bond and diversifies a fundamentally important new direction in the coordination chemistry of phosphorus as an acceptor.通过三甲基膦（Me₃P）对二甲基硫代磷鎓阳离子（dimethylthiophosphonium cation）所连的4-二甲氨基吡啶（4-(dimethylamino)pyridine）配体进行定量交换，该反应证实了N-P键与P-P键的配位属性，同时为以磷作为受体的配位化学这一兼具基础重要性的新兴研究方向拓展了研究维度。
