A process for preparing cyclic phosphonic monesters comprising subjecting aryloxyphosphines of defined formulae to flash pyrolysis, is provided. The aryloxyphosphines are those having the general formula
where Ar is aryl and R is a hydrocarbyl radical capable of forming unsaturated hydrocarbon on severance of the C-O linkages.
本发明提供了一种制备环状膦单体的工艺,包括将定义式的芳氧基膦进行闪速热解。芳氧基膦是通式为
其中 Ar 为芳基,R 为烃基,在切断 C-O 连接时能形成不饱和烃。
