Reactions of dialkyl phosphites (DAP, 1a,b) and trialkyl phosphites (TAP, 2a,b) with the α,β-unsaturated nitriles (3a,b and 4a,b) as well as with anils (5a and 6) derived from aromatic aldehydes (vanillin and/or piperonal) are reported. Structures of the new phosphonate products (cf. 7,8,15,16 and 17) were based upon compatible elementary and spectroscopic results. Tervalent phosphites (TAP, 2a,b) and triphenylphosphine convert vanillin-oxime (Sb) into 4-hydroxy -3-methoxybenzonitrile (19). Possible reaction mechanisms to account for formation of compounds 7a-d, 8a,b and 19 were also postulated.
