摘要：

Tris(tetramethylcyclopentadienyl)aluminum, Cp(3)'Al (Cp' = C(5)Me(4)H), reacts with t-butyl isocyaniode to form (eta(1)-C(5)Me(4)H)(2)Al{c(=NtBu)-C(=NtBu)(C(5)Me(4)H)} which results from the double insertion of the isonitrile at a single Al-cyclopentadienyl ring position. Double isonitrile insertion occurs in preference to a single insertion such that only unreacted Cp(3)'Al and the title compound are observed when fewer than two equivalents of the isonitrile are consumed. The molecular structure of (eta(1)-C(5)Me(4)H)2Al{C(=NtBu)-C(=NtBu)(C(5)Me(4)H)} has been determined by single-crystal X-ray diffraction. The aluminum center is tetracoordinate with two eta(1)-cyclopentadienyl rings and the coupled isonitrile fragment bonding through a carbon of one iminoacyl group and a nitrogen of the other to form a four-membered azametallacycle.
