Reaction of triethylphosphite with a series of α,β-unsaturated esters, ketones, aldehydes, amides and nitriles in protonating solvents proceeds smoothly to furnish β-substituted phosphonate esters. This process, termed hydrophosphinylation, is quite general in contrast to reduction and reductive dimerization, the alternative reaction pathways previously observed for dibenzoylethylene. The most active

P(V)-2,2,2-triethoxy-2,2-dihydro-5-methoxy-1,2 lambda(5)-oxaphospholene was synthesized as a new type of enolate which was hydrolyzed to give a series of phosphonates. In addition, aldol reaction of the oxaphospholene intermediate with several aldehydes as electrophiles under mild and neutral conditions produced phosphonate-containing aldol compounds through a two-step one-pot reaction.
