Synthesis, crystal structure and hydrolysis of novel isomeric cage (P–C/P–O)-phosphoranes on the basis of 4,4,5,5-tetramethyl-2-(2-oxo-1,2-diphenylethoxy)-1,3,2-dioxaphospholane and hexafluoroacetone

Abstract

New rearrangement of P–C-isomer to P–O-isomer in cage phosphoranes series with a high stereoselectivity (>96%) is revealed.
