Abstract

Introduction The preparation of pentaphenylphosphole ( pentaphenylphosphacyclopentadiene) from the reaction between PhPClz and the complex Fez (CO) c (Ph-C2Ph) Z was reported in a previous communication. In order to prove its structure] it also was synthesized by treating 1, 4-dilithiotetraphenylbutadiene
