Reactions of bis(2,2,3,3-tetrafluoropropyl) phosphorisocyanatidite and tris(2,2,3,3-tetrafluoropropyl) phosphite with carbonyl compounds
The authors studied the reactions of bis(2,2,3,3-tetrafluoropropyl) phosphorisocyanatidite with carbonyl and ..cap alpha..-halo carbonyl compounds, namely, benzil, ethyl phenylglyoxylate, methyl chloropyruvate, and diethyl (trichloroacetyl)phosphonate. The reaction of bis(2,2,3,3-tetrachloropropyl) phosphorisocyanatidite with benzil required severe conditions (3 h at 40/sup 0/C). The /sup 31/P NMR spectrum of the reaction mixture contains two signals at 12 and -55 ppm, which probably belong to the azaphospholine and its dimer. By vacuum fractionation they isolated a thick liquid, the /sup 31/P NMR spectrum of which contains a signal 12 ppm corresponding to 5-benzoyl-4-oxo-5-phenyl-2,2-bis(2,2,3,3-tetrafluoropropoxy)-..delta../sup 2/-1,3,2lambda/sup 5/-oxazaphospholine.
