Reactivity correlation of alcohols in hydroalkoxycarbonylation and transesterification reactions
Abstract The alcohol reactivity series in competitive cyclohexene hydroalkoxycarbonylation catalyzed by the Pd(PPh3)2Cl2 complex in the presence of various alcohols was obtained: n-BuOH > n-PrOH > iso-BuOH ≥ CH3OH > C2H5OH > C6H11OH > iso-PrOH > C7H7OH. It was shown that this series correlates well with that of alcohol reactivity in the transesterification reaction. A stronger response of the transesterification rate to alcohol structure is caused by a lower reactivity of esters relative to phosphine acylpalladium complexes responsible for ester formation in the hydroalkoxycarbonylation reaction.
