Wolff Rearrangement
The Wolff Rearrangement allows the generation of ketenes from α-diazoketones. During this reaction an α-diazocarbonyl compound is converted into a ketene by loss of dinitrogen with accompanying 1,2-rearrangement.
Wolff Rearrangement examples catalyzed by cinchona alkaloid derivatives can be found in our free of charge Chiral Catalyst Search.
