摘要：

Radically complex: The photolytic reaction of [Cp*P{W (CO)5}2] (Cp*=C5Me 5) with a diphosphene produces, via a radical intermediate, an air-stable complexed triphosphaallyl radical, in which the unpaired electron is evenly distributed over both terminal P atoms. Oxidation of the radical leads to a triphosphaallyl cation, which is only stable at low temperatures in solution, whereas the stable triphosphaallyl anion is formed by reduction (see picture, Mes*=2,4,6-tri-tert-butylphenyl). © 2009 Wiley-VCH Verlag GmbH & Co.
