Although many secondary reactions exist for this functional group, in the Shapiro reaction in particular water is added resulting in hydrolysis to the alkene.

The Shapiro reaction or tosylhydrazone decomposition is an organic reaction in which a ketone or aldehyde is converted to an alkene through an intermediate hydrazone in the presence of 2 equivalents of strong base.[1][2][3]. Online Version of Record before inclusion in an issue.

This group expels nitrogen leaving a vinyllithium compound.

It may help to improve your hair’s health. Microsoft Internet Explorer 6.0 does not support some functions on Chemie.DE. It is ideal for use by both men and women. The carbanion proceeds in an elimination reaction creating the carbon to carbon double bond and converting the hydrazone group into a lithium diazonium group.

Pennsylvania's Attorney General Josh Shapiro said on Wednesday he is confident a final result from the state's count of votes in the 2020 presidential election will be released soon. Total synthesis of natural products often requires installation of double bond without adding carbon. To directly access fluoroalkenes in good stereoselectivity, a Shapiro fluorination reaction was developed.

This formula claims to address the main causes of hair loss through its powerful ingredients. Current preparations of this functional group commonly provide mixtures of E- or Z-fluoroalkene diastereomers, and/or mixtures of nonfluorinated products. In a prelude to the actual Shapiro reaction a ketone or an aldehyde is reacted with p-toluenesulfonylhydrazide[4] to a p-toluenesulfonylhydrazone (or tosyl hydrazone) which is an imine or hydrazone.

The Bamford-Stevens reaction is also a tosylhydrazone decomposition but in this reaction a much weaker base can only abstract the hydrazone proton and not the α carbonyl proton and the reaction mechanism now involves a carbene or in a protic solvent a carbocation.
