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.
末端炔烃的 Crabbe 同源性可用于使用醛、N,N-二环己胺和催化量的碘化铜 (I) 合成 1,3-二取代丙二烯。这一成功的关键是使用过量的醛和胺,并在微波辐射条件下进行反应。
