Tosylhydrazone
A tosylhydrazone in
tosylhydrazine.[1]
Synthesis
As an example camphor tosylhydrazone is synthesised from
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.
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]
