Co2 grignard reaction
WebApr 7, 2024 · Carbon dioxide is used as a reactant because it is an inert electrophile. Grignard reagent is mainly employed as a strong nucleophile in order to react with \[C{O_2}\] directly and constructs \[C - C\] bonds and lead to the formation of carboxylic acids. Thus, the reaction between \[C{O_2}\] and a Grignard reagent will yield a … WebAfter adding this reagent to carbon dioxide, we obtain benzoic acid after hydrolysis. Introduction: Grignard reagents belong to organometallic compounds. This is a class of …
