Preparation and fate of carbon monosulfide (CS). Ultraviolet photoelectron spectroscopic study of the thermolysis of 5,5-dimethyl-1-phenyl-3-1,3,4-triazoline-2-thione

The results of an ultraviolet photoelectron spectroscopic study of the thermolysis of 5,5-dimethyl-1-phenyl-Δ 3 -1,3,4-triazoline-2-thione (1) are presented. That CS 2 is one of the major products establishes that carbon monosulfide (CS) is formed as a reaction intermediate in the thermolysis. Other products of thermolysis of 1 are molecular nitrogen and isopropylidenephenylamine (2). The photoelectron spectrum of the latter is also reported. …
