Grignard reagents are used to make C-C new bonds. Their reaction with carbonyl compound leads to alcohols. However, when reacted with carboxylic acids carbonyl compounds are formed. Predict what should be the product of the reaction between 4-nitrobenzoic acid and phenyl magnesium bromide and explain in few chosen words why a carbonyl compound instead of an alcohol.
Problem 1. Synthesize the following alkene through the Wittig reaction of a carbonyl compound and a Wittig reagent. 2,3-diphenyl-2-butene 2. Predict the products of the following reactions. Casco CHCH.CHCH, CHCH.CH но ats ОО 2.0 CH,CHACHCH,CHCHOCH.CH, CH 3. A useful and general method for the synthesis of alcohols is the addition of Grignard reagents to carbonyl compounds. Show what Grignard reagent and what carbonyl compound you would start with to prepare the alcohol below. List all possibilities. 2-methyl--butanol 2-METHYL-2- BOTANIC
