Wolf Rearrangement
Define : When an α-diazo ketone is decomposed thermally photo-chemically or catalytically and converted to ketone by removal of dinitrogen, it is called wolf rearrangement. The reaction was given by Ludwing Wolf in 1902. Reaction: When ketene is formed it acts as an intermediate for forming acid Ester and Amide. Mechanism of Wolf Rearrangement: Wolf…
Cannizzaro Reaction
Those carbonyl compound which donot contain α-H react in the presence of conc. base gives alcohol ( reduced product) and acidic salt (oxidized Product). Reaction of cannizzaro: Cannizzaro Reaction Mechanism: Step(01) formation of dianion: In this reaction , we use typical base OH which react on less hindered product because our preference is to make…
