Cw. Ong et al., NITRILE ADDITION TO TRICARBONYLCYCLOHEXADIENYLIUM COMPLEXES - THE EFFECT OF PERCHLORATE COUNTERANION, Tetrahedron letters, 35(34), 1994, pp. 6303-6304
A method for the preparation of the tricarbonylcylohexadienyliumiron p
erchlorate salt and their reactions with TMS-CN were investigated. The
nucleophilic addition reactions of TMS-CN were insensitive to the per
chlorate counteranion since it cannot dissociate into a nucleophlilic
species to release the free cyanide anion. A reductive workup was deve
loped to avoid decompositions.
