A Wittig reagent adds to the carbonyl carbon through the anionic carbon. The intermediate betaine decomposes to give the phosphine oxide and the alkene.










A Grignard reagent will add to a ketone to form a tertiary alcohol.
















Diethylaluminum nitrile is a convenient reagent for the conjugate addition of a nitrile group.









Hydroxylamine adds to ketones & aldehydes to form simple oximes.
