mesyloxymethyl substituent at the vicinal position underwent the Ni(CO)4- induced ring-opening carbonylation reaction with alcohol or amines leading to the γ,δ-unsaturated carboxylic acid derivatives selectively via nickel enolate intermediates. Successful utilization of N,N-dimethyltrimethylsilylamine as an initial nucleophile resulted in condensation with benzaldehyde giving 2-allylcinnamamides.
