Summary

Ph2PCH(Ph)PPh2, prepared by treating Ph2PCH2Ph successively with n-BuLi and Ph2PCl, reacts with group VI metal hexacarbonyls to give [M(CO)4{Ph2PCH(Ph)-PPh2}], where M = Cr, Mo or W. The Cr complex [Cr(CO)4{Ph2PCH(Ph)PPh2}] was deprotonated with MeLi and the resulting carbanion [Cr(CO)4(Ph2-PCPhPPh2)]− acylated with RCOCl (R = Ph or p-tolyl) to give the intensely green title compounds in which an aromatic ring has become a quinonoid.
