Synthesis of fluorinated 2-oxo-1,4,2-oxazaphosphol-4-ines and their opening by alcohols

Trifluoromethyl‐substituted 1,4,2λ5‐oxazaphosphol‐4‐ines from phosphorus dichlorides and N‐acylimines of hexafluoroacetone have been synthesized and characterized by 1H, 19F, and 31P NMR. Alcohols open these oxazaphospholines at the P–O bond, forming the corresponding esters.
