摘要：

A limited number and variety of polyphosphorus cations exist in comparison to their neutral (polyphosphines) and anionic (polyphosphides) counterparts. A general and facile method has now been developed for the preparation of phosphinophosphonium, diphosphinophosphonium, and cyclotetraphosphinophosphonium cations from polyphosphines. Furthermore, the stability of the cyclopentaphosphorus ring is emphasized (see crystal structure of [Ph 6P5]+). (Chemical Equation Presented) © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
