Abstract
The data are presented on the rates of deuteromethanolysis of 2-fluoro-1,3,2-dioxaphosphorinane 1 in the presence of various bases differing in the basicity and of that of 2-amino-1,3,2-dioxaphosphorinanes 2–4 catalysed by hydrogen fluoride salts of different amines. The alcoholysis of the fluorophosphite 1 in the presence of imidazole, N-ethylaniline and 2,6-di-tert-butyl-4-methylpyridine proceeds slowly whereas alcoholysis of the amidoesters 3,4 catalysed by imidazole and N-ethylaniline hydrofluorides occurs rapidly even at room temperature. These data do not match the hypothesis that halophosphites are intermediates in the alcoholysis of amidophosphites in the presence of amine hydrohalides.
