Abstract

original image

Only with a second-row transition metal as the central atom can decamethylmetallocenes [M(C5Me5)2]+ be fully permethylated to give decaisopropylmetallocenes 1. The corresponding rhodium complex, M = Rh, was isolated in 55% yield; in the analogous reaction of the cobalt sandwich complex, a maximum of 14 methyl groups were introduced.
