Electron Impact Mass Spectral Fragmentation Patterns of Two Six-membered Phosphiniminocyclothiazenes, (PH)[(C₆H₁₁)₂N](R₂N)PN-S₃N₃—A Comparison

GRAPHICAL ABSTRACT

Abstract

This study has been directed toward understanding the stability aspects from the mass spectral fragmentation patterns of two phosphiniminocyclotrithiazenes of the type (C₆H₅)[(C₆H₁₁)₂N](R₂N)P˭N−S₃N₃ [R‒Me (1) and n-Bu (2)]. Most of the structural features of the two ring systems considered are comparable for both the heterocycles. Some of the fragments that are formed under the operated mass spectral conditions are SN, S₂N₂, S₃N, S₃N₂, S₃N₃, and S₃N₄, among others. Most of these observed fragments are already known to exist either as stable entities or as oligomerized species, and they are found to possess various applications.
