The reactive 1:1 intermediate obtained from the addition of triphenylphosphine to dibenzoylacetylene was trapped by heterocyclic NH-acids such as imidazole, 4-nitroimidazole, or 5-methyl-4-nitroimidazole to produce 2,3,5-trisubstituted furan derivatives. Using 2-benzoylimidazole or saccharin as NH-a
## Abstract Aromatic amine phosphonato esters **4aโd** were obtained in excellent yields from the 1:1:1 addition reaction between triphenyl phosphite and dimethyl acetylenedicarboxylate in the presence of NHโaromatic amines such as 2โaminobenzophenone, 2โaminoacetophenon, methylโ2โaminobenzoate, an
