Notes:
The mass spectra of maleic, fumaric, citraconic, mesaconic and itaconic diamides have been studied. In the molecular ions of the cis isomers, amide-amide interaction does take place, analogous to but less pronounced than, the carboxyl-carboxyl interaction of the corresponding acids.In spite of the weaker interaction a prominent loss of CONH from the molecular ion of a diamide would be strong evidence in support of a cis or similarly rigid geometrical arrangement of the amide groups. The mass spectra of maleic and fumaric nitriles are also reported.
