The Crabbe homologation of terminal alkynes could be applied to the synthesis of 1,3-disubstituted allenes using aldehydes, N,N-dicyclohexylamine, and a catalytic amount of copper(I) iodide. The key to this success was the employment of an excess of aldehyde and amine, and performing the reaction under microwave irradiation conditions.
