A scheme is developed for synthesizing 14C labelled α-acetates of secondary α-hydroxylated nitrosamines. In this manner 14C-methyl (1-acetoxy)ethyl nitrosamine and 1-14C-ethyl (1-acetoxy)ethyl nitrosamine are synthesized in 16.3 and 33.3% yield, radiochemically pure.

has been studied with a view toward elucidating mechanistic details and effects of structure on mechanism and reactivity. Rate constants (k1) for the pH-independent decay of 43 α-(acyloxy)dialkylnitrosamines have been determined. Observations from these and other experiments rule out decomposition via an anchimericassistance mechanism involving the Z isomer that had previously been suggested. All
