SELECTIVE SYNTHESIS OF γ,δ-UNSATURATED CARBOXYLIC ACID DERIVATIVES BY THE NI(CO)4-INDUCED RING-OPENING CARBONYLATION REACTION

Article abstract of DOI:10.1016/S0040-4039(00)98929-9

gem-Dibromocyclopropanes bearing the chloromethyl or 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 sel
