Abstract In the reactions of dimethyldioxirane (1a) and methyl (trifluoromethyl) dioxirane (1b) with 2, 2, 6, 6-tetramethylpiperidinyl-1-oxyl (2)(TEMPO) in acetone, the corresponding methoxyamine 1-methoxy-2, 2, 6, 6-tetramethylpiperidine (5) is produced in≥ 98% yield, both in air and under N 2, and in the absence or presence of a hydrocarbon (adamantane). Kinetic experiments show that aminoxyl 2 triggers the radical decomposition of the ...
