A Facile Zinc(II) Chloride Assisted Desulfurization of High‐Nitrogen Heterocycles

High‐nitrogen heterocycles are important to fields as diverse as pharmaceuticals and energetic materials. However, their synthesis can often be inconvenient or involve toxic precursors. In this work, we synthesize 1‐substituted‐5 H ‐tetrazoles via the desulfurization of readily available 1‐substituted‐1 H ‐tetrazole‐5‐thiones via a zinc chloride assisted desulfurization providing a new, safe, and efficient process with higher yields than the traditional desulfurization methods.
