stoichiometric amount of boron trifluoride etherate yields the corresponding tert-alkyldiphenylphosphine despite the coexistence of the strong Lewis acid and the highly coordinating phosphine. Use of diphenyl(trimethylsilyl)phosphine as a nucleophile makes the reaction catalytic in boron trifluoride.
[反应:见正文]尽管存在强路易斯酸和高度配位的膦,但在化学计量的三氟化硼醚化物存在下,用二苯膦处理叔烷基氟可以得到相应的叔烷基二苯膦。使用二苯基(三甲基甲硅烷基)膦作为亲核试剂可使反应在三氟化硼中催化。
