摘要：

The reaction of R(C=O)Cl with 1,2-(Me3SiLiP)2C6H4 (1) ends in formation of 2-organo-substituted 1,3-benzodiphosphole anions, {A figure is presented} (2-5) which can be stabilized as η1- or η5-coordinated moieties. Whereas the interaction of 5 (R = t-Bu) with C-electrophiles (EtBr, R(C=O)Cl) results in stable 1,3-benzodiphospholes, with HCl, Me3SiCl or Ph2PCl the primarily formed heterocycles of this type migrate in a [1,2]-substituent shift. 31P NMR data of the compounds prepared are discussed. The results suggest a nonaromatic character of 1,3-benzodiphospholes. © 1990.
