-arsine with tetrakistrifluoromethyl-diphosphine and -diarsine gave the mixed fluoroalkyl-alkyl derivatives (CF3)2P·P(CH3)2, (CF3)2As·P(CH3)2, (CF3)2P·As(CH3)2, and (CF3)2As·As(CH3)2 containing P–P, As–P, and As–As bonds. The reactions appear to depend on the basic strength of the hydride since the fully fluorinated phosphino-arsine (CF3)2P·As(CF3)2 was obtained from the action of bistrifluoromethylarsine
二甲基膦和-ar与四三氟甲基-二膦和-二氮烷反应,得到混合的氟代烷基-烷基衍生物(CF 3)2 P·P(CH 3)2,(CF 3)2 As·P(CH 3)2,含有(CF 3)2 P·As(CH 3)2和(CF 3)2 As·As(CH 3)2含有P–P,As–P和As–As键。反应似乎取决于氢化物的基本强度,因为完全氟化的膦基s基(CF 3)2通过双三氟甲基3对四三氟甲基二膦的作用获得了P·As(CF 3)2,但是二ar基不受双三氟甲基膦的影响。同样由双三氟甲基碘-膦和-s的混合物与汞反应得到的全氟化膦-s不能从二磷和二砷化合物中分离出来,并进行了光谱表征。讨论了化合物的核磁共振谱和质谱的有趣特征。
