The reaction between alkylaminobis(trifluoromethyl)phosphines, RNH·P(CF3)2, and boron trihalides is complex and the products depend on the reaction conditions and on the nature of both the alkyl group and the boron trihalide. At low temperatures 1:1 adducts are formed but at room temperature the predominant reaction is cleavage of the N–P bond to give halogenobis(trifluoromethyl)phosphines, (CF3)2PX
烷基氨基双(三氟甲基)膦,RNH·P(CF 3)2和三卤化硼之间的反应是复杂的,并且产物取决于反应条件以及烷基和三卤化硼两者的性质。在低温下会形成1:1的加合物,但在室温下,主要反应是裂解N–P键以生成卤代双(三氟甲基)膦,(CF 3)2 PX和烷基氨基硼–卤素化合物:在–78°: RNH·P(CF 3)2 + BX 3 = RNH·P(CF 3)2,BX 3在25°:RNH·P(CF 3)2 + BX 3=(CF 3)2 PX + RNH·BX 2,其中R = Bu t,X = F或Cl。当R = Me或Et时,第二反应的氨基硼产物歧化成三卤化硼加合物和相应的硼嗪:2RNH·BX 2= RNH 2,BX 3 +⅓(RNBX)3
