Abstract

The generation of mono- and I,1'-dilithioferrocenes by transmetalation of butyl ferrocenyl tellurides 3 and 5 is reported; these intermediates and the mono-transmetalation species from 5 provide new alternative and improved routes for the preparation of pure substituted ferrocenes 4, 6, 7, and 8.
