1,1-Dibromo-2-chlorocyclopropanes underwent the Ni (CO)4-induced ring-opening carbonylation reaction with alcohol or amine giving the β, γ,-unsaturated carboxylic acid and dicarboxylic acid derivatives. Use of N,N-dimethyltrimethylsilylamine as an initial nucleophile in the presence of benzaldehyde led to a dienecarboxamide presumably via codensation of the nickel enolate intermediate.
