The room-temperature hydrophosphinylation of unactivated monosubstituted alkenes using phosphinates (ROP(O)H2) and catalytic NiCl2 in the presence of dppe is described. The method is competitive with prior palladium-catalyzed reactions and uses a much cheaper catalyst and simple conditions. The scope of the reaction is quite broad in terms of unactivated terminal olefins, proceeds at room temperature
描述了在
次磷酸酯存在下使用
次膦酸酯(ROP(O)H 2)和催化NiCl 2进行的未活化单取代烯烃的室温氢次膦酰基化。该方法与现有的
钯催化反应具有竞争性,并且使用便宜得多的催化剂和简单的条件。就未活化的末端烯烃而言,反应的范围很广,在室温下进行,通常避免色谱纯化,并允许一锅转化为各种有机
磷化合物。
