MASS-SPECTRAL BEHAVIOR AND THERMAL STABILITY OF HETARYL ANALOGS OF UNSYMMETRICAL BENZOINS

Abstract

The main path in the mass-spectral dissociation of  the hetaryl analogs of unsymmetrical benzoins is β-fragmentation with cleavage of the central C–C bond. Here, the strongest peak in the mass spectra of α-benzoins is the peak of the hydroxymethylhetaryl cation, and in  β-benzoins it is the peak of the hetaroyl cation. The thermal α → β isomerization of the hetaryl analogs of benzoin was studied. In the
case of indole and pyrrole derivatives the formation of polyheterocyclic systems is observed.
