摘要：

(Figure Presented) Methylation or phosphenium insertion reactions with cyclopolyphosphines (PtBu)3 or (PCy)4 (Cy = cyclohexyl) are presented as stereospecific and high-yielding preparative approaches to cyclopolyphosphinophosphonium cations. The cations [(PtBu)3Me] +, [(PCy)4Me]+, and [(PtBu)3PMe 2]+ (see picture; P orange, C gray) are prepared as trifluoromethane-sulfonate salts and represent key frameworks in fundamental catena-phosphorus chemistry. © 2005 Wiley-VCH Verlag GmbH & Co.
