includes the first cyclization of a nitrilimine with a diazonium species, giving a tetrazole, a previously unknown transformation, as well as leading to the creation of several new energeticmaterials with backbones not available by traditional techniques. New materials prepared were characterized both chemically (multinuclear NMR, IR, mass spectrometry, and elemental analysis) and energetically, with sensitivities

A preparative method of synthesis of N6-α-haloacyl sydnoneimine derivatives has been developed. These compounds are convenient intermediates for the synthesis of a large variety of N6-α-amino-substituted and N6-α-thio-substituted acyl derivatives of sydnoneimines. The obtained sydnoneimine derivatives may be of interest in the context of searching for new physiologically active compounds.

A highly efficient gram-scale method for the C(4)-functionalization of sydnone imine hydrochloride derivatives was developed. This new approach was realized through consecutive reactions including the preparation of a C(3)-substituted N6-tert-butoxycarbonyl sydnone imine derivative, deprotonation with n-BuLi and reaction of the lithiated-intermediate with an electrophilic agent, and removal of the
