Rh-catalyzed intermolecular hydroacylation between salicylaldehyde and alkenylnitriles proceeded at roomtemperature to preferentially give normal-hydroacylated products. Addition of CH3CN and NaOAcaccelerated the Rh-catalyzed hydroacylation of monoolefins to exclusively produce the normal-hydroacylated products under mild reaction conditions. Plausible mechanisms for the regioselections arealso described.
