THE MASS SPECTRAL FRAGMENTATION OF N,N-DITHIOBISAMINES AND THEIR CYCLIC ANALOGUES 3,6-DIALKYL-1,2,4,5,3,6-TETRATHIADIAZINES

Abstract

The mass spectra of the series of compounds R₂NSSNR₂ where and N(CH₂-C₆H₅)₂ and of its cyclic analogues RN(S₂)₂NR where R-CH₃, C₆H₁₁ and CH₂-C₆H₅ are presented and discussed. The major fragmentation modes of these compounds involves the cleavage of the C-N, S-N and S-S bonds. The nature of the fragments containing sulfur atoms, arising from S-N and S-40 rupture, is dependent on the cyclic or acyclic structure of the compounds.

Key Words:

• N,N′-dithiobisamines
• 3,6-dialkyl-1,2,4,5,3,6–tetrathiadiazines
• mass spectra
• disulfide compounds S-S cleavage, S-N cleavage.
