Abstract

While, in general, decamethylzincocene, Zn (C5Me5) 2, and other zincocenes, Zn (C5Me4R) 2 (R= H, Bu t, SiMe3), react with dialkyl and diaryl derivatives, ZnR'2, to give the half-sandwich compounds (η5-C5Me4R) ZnR', under certain conditions the reactions of Zn (C5Me5) 2 with ZnEt2 or ZnPh2 produce unexpectedly the dizincocene Zn2 (η5-C5Me5) 2 (1) in low yields, most likely as a result of the coupling of two (η5-C5Me5) Zn radicals.
