of N-aminopyrrolidine 5 with tert-butyl hypochlorite at -130 o C yields the 1,1-disubstituted diazene which is stable in dimethyl ether solution at this temperature. Thermal (-90 o C) or photochemical (-130 o C, λ>330 nm) decomposition of 4 fumishes singlet alkyl propargyl biradical 1, which undergoes fragmentation to 16, cyclization to 17, and disproportionation to 18 and 19 (Table I)
N-氨基吡咯烷 5 与次氯酸叔丁酯在 -130 o C 下氧化生成 1,1-二取代的二氮烯,该温度在二甲醚溶液中是稳定的。4 个 fumishes 单线态烷基炔丙基双自由基 1 的热(-90 o C)或光化学(-130 o C,λ> 330 nm)分解,经过裂解为 16,环化为 17,歧化为 18 和 19(表 I)
