An additive-free strategy has been developed for the synthesis of α-keton thiol esters through direct oxyacylthiolation of vinyl azides with thioacids and water. The C-S and CO bonds were formed in a one-pot operation via a radical reaction pathway.

Synthesis of thiazoles from vinyl azides and xanthates under the action of an Mn(III)-oxidant.
Organic and biomolecular chemistryReaction of xanthates and vinyl azides under the action of Mn(OAc)3 results in the formation of alkoxy thiazoles. In this transformation, potassium xanthate undergoes Mn-mediated oxidation, generating the corresponding xanthyl radical.

Angewandte Chemie International Edition in English, 1975
AbstractThis review is designed to demonstrate the versatility of vinyl azides in organic reactions. The reactive azide function is susceptible to thermolysis, photolysis, cycloadditions, and attack by nucleophiles and electrophiles. The neighboring double bond accentuates the reactivity of the azide function and provides additional intramolecular ...
