Interaction of ethyl-2-cyanoacrylate 1 with trivalentphosphoruscompounds can cause not only polymerization of 1, but under established conditions it affords, depending on the structure of the latter, betaines 3, spirophosphoranes 5, i.e. phosphorylated at the carbonyl oxygen esters of 2-cyanopropionic acid or 2-cyano-3-phosphoranylpropionates 9.

The syntheses of various aliphatic, aromatic, sterically hindered, and cyclic organophosphorus compounds (phosphorous acid esters, ester chlorides and ester amides, hydrogen phosphites, phosphonates and phosphates) are reported, and general procedures for preparation are given.The compounds synthesized were investigated by means of P-31-, H-1- and C-13-n.m.r. spectroscopy, and the chemical shifts measured are listed.
