Reactions

Hydrolysis is the reverse reaction of formation with regeneration of the carbonyl compound.

In the

reduced to the corresponding alkanes with reagents such as sodium borohydride and borane
.

Tosylhydrazone salts can react with metals to form

metal carbene
through the diazo intermediate.

Cyclopropanation

Tosylhydrazones are also starting materials for certain

diazo
intermediateformed by decomposition of the tosylhydrazone forms a palladium-carbene complex with the oxidative addition complex of palladium with the aryl halide. Using this powerful method it is possible to access bioactive compounds.[9] [10]
