Abstract

Dialkyl phosphites (2a–c) react with furfurylidenemalonitrile (1) to give the corresponding 1:1 phosphonate adducts 3a–c. On the other hand, trialkyl phosphites (6a, b) affected C‐alkylation of the exocyclic ethylenic linkage in compound (1) to give the respective phosphonate 7a, b.

In a continuation of our studies on the reactions of trivalent phosphorus nucleophiles with quinonediimides2 we have investigated the reactions of di-and tri-alkyl phosphites with p quinonediaulfonimides3. The latter, like pquinoncs, react with C, N, 0 or S nucleophiles to give products in which the
