摘要

Abstract Thermal decompositions of S-2-benzothiazole thiocarbonates have been investigated. The results are best rationalized by an Sni ion-pair return mechanism from which S-substituted benzothiazoles are the major products obtained. The ready ionization of the carbon-oxygen bond of thiocarbonates at elevated temperature renders a concerted Sni mechanism (internal substitution with allylic rearrangement) inoperative. Of particular ...
