- 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.When trans-2-chloro-1-cyclohexanol is treated with a base, cyclohexene oxide is the product. However, when cis-2-chloro-1-cyclohexanol is treated with a base, the product is cyclohexanone.
