We have succeeded in the synthesis of propargyl azides containing 1- or 3-phenylthio functionalities. The selective oxidation of their sulfur atoms to sulfoxides and sulfones allows access to the first propargyl azides bearing acceptor substituents. Inter
First successful synthesis, isolation and characterization of open-chain 1,2-diazidoethenes

Open-chain 1,2-diazidoethenes have been obtained from the recently reported acceptor-substituted propargyl azides by one-pot reactions with tetramethylguanidinium azide (TMGA) and in some cases via a two-step procedure starting with in situ production of the corresponding azidoallene followed by addition of hydrazoic acid with the help of TMGA. In a different synthetic pathway, the substitution reactions between 2-azido-3-haloacroleins and hexadecyltributylphosphonium azide (QN3) have been used. In order to have more evidence for their structures, some diazido compounds were converted to their bis-triazole derivatives through 1,3-dipolar cycloaddition.
