Abstract

The 2,4-di-tert-butyl-6-methylphenyl substituent was placed on phosphorus of a phosphole, causing restricted rotation about the P-C bond and flattening of the phosphorus pyramid. Electron delocalization was greater in this phosphole as a result of the flattening. The 7-phosphanorbomene with this substituent had the most deshielded 31p nucleus ever recorded in this series, and thermally decomposed with formation of a diphosphene, suggesting a phosphinidene intermediate.
