ABSTRACT
A series of novel synthetically important reactions has been developed for the quick convenient and high-yield preparation of trimethylsilyl diphenylphosphinite, a valuable for the synthesis of functionalized alkyldiphenylphosphine oxide by Arbuzov reaction. Initial compounds are (1-hydroxy-1-methylethyl)diphenylphosphine oxide and hexamethyldisilazane, bis(trimethylsilyl)acetamide, diethyl(trimethylsilyl)amine, trimethylchlorosilane.
