A known base-induced catalytic ketoform synthesis can now be carried out without sacrificing the directivity of the prior art process, but non-catalytically, that is, in the absence of the phase transfer catalyst heretofore required, provided the ketone/araldehyde is present in large excess from about 2 to about 25 times the calculated molar amount necessary to yield the reaction product. This synthesis obviates the problems of separating and recovering a phase transfer catalyst used in the prior art process.
现在可以进行已知的碱诱导催化酮醛合成,而不牺牲现有技术工艺的直接性,但不需要催化剂,也就是说,在没有以前所需的相转移催化剂的情况下,只要酮/醛大量过量存在,过量量约为生成反应产物所需的计算摩尔量的 2 至 25 倍。这种合成方法避免了分离和回收现有工艺中使用的相转移催化剂的问题。
