Abstract
The mass spectra of a number of S- and N-acylalkyl derivatives of 2-mercaptobenzimidazole were studied in order to investigate the ring-chain tautomerism of compounds of this group. It is shown that the fragmentation of the investigated compounds takes place from the open form of the molecular ion. The data obtained in this study are compared with the results of studies of the tautomeric equilibria in very dilute solutions. The principal fragmentation regularities were established.
