Grignard reagents react with a variety of carbonyl derivatives. The most common application of Grignard reagents is the alkylation of aldehydes and ketones, i.e. the Grignard reaction: Note that the acetal function (a protected carbonyl) does not react. Such reactions usually involve an aqueous acidic workup, though this step is r… Web(Grignard reagents) Two important types of organometallics used as carbon nuclephiles are the acetylides (ch. 9) and the Grignard reagents (ch. 10). More ... In the acid-catalyzed tautomerization, the alkene acts as a base and a proton from the acid is added to the p-bond with formation of the most stable carbocation.
