Abstract

M (η6-arene) 2 species (M= Cr, arene= 1, 3, 5-Me3C6H3; M= Mo, arene= 1, 3, 5-Me3C6H3, 1, 3, 5-iPr3C6H3), have been prepared by a modified Fischer–Hafner synthesis or by metal vapour techniques. The reaction of Cr (η6-1, 3, 5-Me3C6H3) 2 with the fulvene derivatives pentacarbomethoxycyclopentadiene (pcmcpH), 1-benzoyl-6-hydroxy-6-phenylfulvene (dbcpH), or 1-benzoyl-3-nitro-6-hydroxy-6-phenylfulvene (dbncpH) proceeds with ...
