1. By direct analysis of daughter ions, a study has been made of the paths of fragmentation of the molecular and fragment ions manifested in the mass spectra of arylidene derivatives of barbituric acid and 2-thioxy-4-thiazolidone. It has been shown that the fragmentation of these compounds proceeds through decomposition of the heterocyclic part and the substituents of the aryl part of the molecule. 2. It has been shown that the condensation of barbituric acid and 2-thioxy-4-thiazolidone with o-hydroxyaryl aldehydes proceeds with the formation of anomalous products, the structure of which has been established from an analysis of the spectral data.
