- b) The Wolf-Kishner reduction is a reaction used in Organic Chemistry to convert carbonyl functionalities into methylene group. The reaction was used to convert an aldehyde or ketone to an alkane using hydrazine, base and thermal conditions. The mechanism begins with the attack of hydrazine of the aldehyde or ketone. Stage 1: The reaction of aldehyde/ketone with hydrazine to produce hydrazine Stage 2: Reaction with the base and heat to convert hydrozone to alkane Write the mechanism of the reaction.arrow_forwardGive the product for each step in the reactionarrow_forwardIdentify the best reagents to complete the following reaction.arrow_forward
- The Stork reaction is a condensation reaction between an enamine donor and an α,β-unsaturated carbonyl acceptor. The overall reaction consists of a three-step sequence of formation of an enamine from a ketone, Michael addition to an α,β-unsaturated carbonyl compound, and hydrolysis of the enamine in dilute acid to regenerate the ketone.
