The difficulties which in the past have precluded controlled acetalization of an α,β-unsaturated ketone functionality in the presence of a saturated carbonyl group can be overcome simply by making recourse to 2,4,6-collidinium p-toluenesulfonate as catalyst.
过去难以通过在饱和羰基存在下控制α,β-不饱和酮官能团进行缩醛化的困难,可以简单地通过使用对甲苯磺酸2,4,6- collidinium对甲苯磺酸盐作为催化剂来克服。
