Reactions of bis(trifluoromethyl)nitroxyl with a number of methyl- and trifluoromethyl- substituted arsines and stibines at room temperature lead to the formation of pentavalent arsenic and antimony derivatives, namely (CH3)3−n(CF3)nM[ON(CF3)2]2 (M = As, n = 0, 1, 2; M = Sb, n = 0, 1). The derivatives yield bis(trifluoromethyl)- hydroxylamine and the corresponding dichlorides on treatment with hydrogen
在室温下,双(三氟甲基)硝基甲苯与许多甲基和三氟甲基取代的rs和stibines反应导致形成五价砷和锑衍生物,即(CH 3)3-n(CF 3)n M [ON (CF 3)2 ] 2(M = As,n = 0,1、2; M = Sb,n = 0,1)。该衍生物在用氯化氢处理时产生双(三氟甲基)-羟胺和相应的二氯化物。提出了用于氧化加成反应的自由基机理。
