O-Nitrosobis(trifluoromethyl)hydroxylamine gives novel reactions with tris(trifluoromethyl)phosphine, -arsine and -stibine to afford mainly the corresponding bis(trifluoromethyl)nitroxy derivatives. Tris(trifluoromethyl)phosphine affords (CF3)2NOP(O)(CF3)2 and (CF3)2NNO. Tris(trifluoromethyl)arsine also gives (CF3)2NNO in high yield, together with smaller amounts of (CF3)2NOAs(CF3)2, CF3N = CF2, COF2
O-亚硝基双(三氟甲基)羟胺与三(三氟甲基)膦,-ar基和-二苯乙烯生成新的反应,主要得到相应的双(三氟甲基)硝基氧基衍生物。三(三氟甲基)膦提供(CF 3)2 NOP(O)(CF 3)2和(CF 3)2 NNO。三(三氟甲基)a还可以高收率产生(CF 3)2 NNO,以及少量(CF 3)2 NOA(CF 3)2,CF 3 N = CF 2,COF 2三(三氟甲基)锑,不发生氧化反应或加成反应。而是以高收率获得了[(CF 3)2 NO] 3 Sb和[(CF 3)NO] 2 SbCF 3。反应的化学计量表明,与锑键合的双(三氟甲基)硝基氧基的额外量源自与锑键合的三氟甲基。然而,O-亚硝基双(三氟甲基)羟胺在室温下与1,1-二氟-2,2-二氯乙烯和1,1-二氟-2-氟-2-溴乙烯一起生成加成产物。提出了使涉及V族化合物的上述反应合理化的机理。
