Tertiary phosphines are prepared by reacting a phosphine (PH
3
or a primary or secondary phosphine) with a cyclic alpha,beta-unsaturated carbonyl compound having no more than one C═C double bond conjugated with a carbonyl group. The inventive tertiary phosphines can have R groups that are the same or different. The inventive tertiary phosphines may be used as ligands for metal catalysts or as starting materials for preparing phosphonium salts or ylids.
三级膦可以通过将膦(PH3或一级或二级膦)与具有不超过一个C═C双键与羰基共轭的环状α,β-不饱和羰基化合物反应制备。创新的三级膦可以具有相同或不同的R基。这些创新的三级膦可以用作
金属催化剂的
配体或用作制备膦盐或膦叶立德的起始材料。
