Abstract: | Summary. The reaction of dibenzoyldiazine with phosphorus ylides afforded the new 2-(benzoylhydrazono)phenylalkyl]but-2-enedioic acid
dialkylesters. Moreover, ethyl-2(triphenylphosphoranylidene)propionate reacts with dibenzoyldiazine to give the olefinic compound
and triphenylphosphine oxide. On the other hand, oxovinylidene-triphenylphosphorane reacts with dibenzoyldiazine to give a
new phosphorane adduct. Trialkyl phosphites react with dibenzoyldiazine to yield the dialkyl phosphonate products. The reaction
of dibenzoylhydrazide with Wittig reagents gave rise to the new 3,7-diphenylpyrazolo1,2-α]pyrazole-1,5-diones. Possible reaction mechanisms are considered,
and the structural assignments are based on analytical and spectroscopic results. |
