Cro3 organic chemistry
WebThe oxidation of an alcohol to form an aldehyde or ketone is very important in synthesis. In this process, the hydroxy hydrogen of the alcohol is replaced by a leaving group (X in the figure below). Then, a base can abstract the proton bound to the alcohol carbon, which results in elimination of the X leaving group and formation of a new carbon ...
