This compound is a tosylhydrazone derivative, primarily used as an intermediate in organic synthesis. It is formed from the condensation of 1,2-diphenylethanone (deoxybenzoin) with 4-methylbenzenesulfonohydrazide. Key applications include the Bamford–Stevens reaction, where it decomposes to form alkenes via diazo intermediates, and the Shapiro reaction for generating vinyllithium species. It is also employed in the synthesis of diazo compounds for cyclopropanation and other transformations. This reagent is valuable in pharmaceutical research and fine chemical production for constructing complex molecular architectures.
