Recyclization of 2-amino-4,4-dimethyl-Δ2-1,3,4-thiadiazolin-4-io-5-acetates into 2-dimethyl-hydrazono-2,3-dihydro-4h-1,3-thiazin-4-ones

Abstract

2-Amino-4,4-dimethyl-δ 2-1,3,4-thiadiazolinio-5-acetates were found to recyclize into 2-dimethylhydrazono-2,3-dihydro-4H-1,3-thiazin-4-ones. The similar mass fragmentation of these compounds is explained by the occurrence of a rearrangement under electron impact which is analogous to the chemical recyclization thiadiazolinioacetates.
