3 (45% on oxyl) and a complex higher-boiling mixture, from which only the substitution product (CF3)2NOCH2CMePh2 (7) (36% on arene) could be isolated. In contrast, the reaction of oxyl 1 with benzylcyclopropane at room temperature is clean and gives hydroxylamine 3 (49% on oxyl) and the substitution product CH2CH2CHCH(Ph)ON(CF3)2 (8) (95% on cyclopropane). From the reactions of oxyl 1 with 2-phenylpropan-2-ol
