WebEsters react with two moles of a Grignard reagent to give tertiary alcohols (Fig. 12-27). Figure 12-27. Tertiary alcohols are formed from esters by reaction with a Grignard reagent. The addition of one mole of Grignard reagent to the carbon-oxygen double bond gives an unstable intermediate that breaks down to a ketone. WebGeneral Principles of the Grignard Reaction The Grignard reaction is one of the more important classical methods for forming carbon-carbon bonds. It is a two step process: first the Grignard reagent is prepared and then it is reacted with a suitable carbonyl-containing compound. Grignard reagents are prepared (eq. 1) from alkyl halides
