Efficient intermolecular hydroacylation of 1-alkene with aliphatic aldehyde was achieved using a catalyst mixture of cyclohexylamine, p-trifluoromethylbenzoic acid, Wilkinson's complex and 2-amino-3-picoline. The formation of unwanted aldol side-product was avoided through the conjugate addition of cyclohexylamine to the aldol intermediate that was initially generated, followed by the retro-Mannich-type fragmentation of the resulting β-aminoaldimine.
