Unexpected reaction of 2-chloro-l-propen-3-yl isothiuronium chloride with potassium ditelluride: the first example of vicinal elimination of chlorine and sulfur-bearing moieties

摘要

2-Chloro-l-propen-3-yl isothiuronium chloride reacts with potassium ditelluride in hydrazine hydrate to afford elemental tellurium and allene. The latter is formed due to the vicinal elimination of chlorine and a sulfur-bearing moiety.
