constants for the decomposition of (E)-methanediazoate (1) at 25 o C, ionic strength 1 M (NaClO 4 ), are independent of the concentration of nucleophile in up to 0.25 M propylamine base, 0.5 Mmethoxyamine base, 0.20 M thiosulfate dianion, and 0.50 M azide ion. When the CH 3 group of 1 is transferred to benzoate ions, benzyl alcohol, and water upon decomposition in near neutral D 2 O solutions, the isotopic
(E)-甲烷重氮酸盐 (1) 在 25 o C、离子强度 1 M (NaClO 4 ) 下的分解速率常数与亲核试剂在高达 0.25 M 丙胺碱、0.5 M甲氧胺碱、0.20 M 硫代硫酸盐中的浓度无关二价阴离子和 0.50 M 叠氮离子。当 CH 3 基团 1 在接近中性的 D 2 O 溶液中分解后转移为苯甲酸根离子、苯甲醇和水时,甲基的同位素完整性保持在 70-90% 的程度
