wolf kishner reduction , mechanism, reagent

In wolf kisna reduction carbonyl compounds reduced to hydrocarbon.

 the reaction occurs in two step in first step carbonyl compound converted to hydrazone using reagent hydragene in acidic medium .

In the second step hydrogone converted to corresponding hydrocarbon using reagent NaoEt/EtoH.

Mechanism: in first step hydrazine reacts with carbonyl compound to form hydrazone where hydrogen act as a nucleophile which attack electrophilic centre ofcarbonyl carbon and further more water is removed.

in second step the base abstracts a proton from hydrazone to form a diimide and that is the rate determining step then the diimide losses another proton to form a carbo anions which rapidly takes up proton from the solvent ,alcohol formed in the process to form the hydrocarbon.
