Abstract

The addition of a variety of the highly functionalized zinc-copper reagents RCu(CN)ZnI to the title cation gives (η 6 -cyclohepta-1,3,5- triene)Cr(CO) 3 complexes with a functionalized side chain at the C-7 position of the ring: intramolecular cyclisation of ester-substituted adducts using lithium diisopropylamide generates fused bicyclo-[5.3.0]decane and -[5.4.0]undecane derivatives.
