Question

Quizplus · Accepted Answer

The Wittig reaction is a useful tool for the direct conversion of aldehydes and ketones to alkenes. This is accomplished through the use of a phosphorous ylide, which upon reaction with the carbonyl compound, results in formation of an oxaphosphetane intermediate. The intermediate then undergoes a series of rearrangements and ultimately yields an alkene product.
