The reactivity of diphenylvinylphosphine towards nitrones is dominated by the dipolarophilic nature of its double bond rather than by the ability of the PIII to act as an oxygen acceptor.
REGIOCHEMICAL STEERING AND ASSIGNMENT IN CYCLOADDITIONS OF NITRONES TO DIPHENYLVINYLPHOSPHINE OXIDE

, p. 135 - 138 (2007/10/02)
In 1,3-dipolar cycloaddition of C,N-diphenylnitrone to diphenylvinylphosphine oxide ( and also to diphenylvinylphophine sulphide) the 4-substituted phosphinyl isooxazolidine is formed predominantly and in the case of a cylic nitrone the 5-substituted regioisomer prevails.Regiochemical distinctions between the isomeric phosphinyl isoxazolidines are best executed by means of (13)C NMR spectroscopy. Key words: 1,3-dipolar cycloaddition; diphenylvinylphosphine oxide, C,N-diphenyl nitrone; phosphinyloxazolidine, regioselective addition.
