WebReaction mechanism. In a prelude to the actual Shapiro reaction, a ketone or an aldehyde (1) is reacted with p-toluenesulfonylhydrazide (2) to form a p-toluenesulfonylhydrazone (or tosylhydrazone) which is a hydrazone (3).Two equivalents of strong base such as n-butyllithium abstract the proton from the hydrazone (4) followed by the less acidic proton … Web13 jan. 2024 · This chapter discusses the reactions of aldehydes and ketones and their derivatives.
