Vedclass · Answer

(A) The reaction involves a nucleophilic addition of a di-Grignard reagent to a diketone. The two $MgBr$ groups act as nucleophilic centers that attack the two carbonyl carbons of acetylacetone $(CH_3COCH_2COCH_3)$.This cyclization reaction forms a cyclic di-alkoxide intermediate.Upon hydrolysis with $H_2O$,the alkoxide groups are protonated to form the corresponding diol.The final product $B$ is $1,3$-dimethylcyclopentane-$1,3$-diol.

Consider the above reaction sequence and identify the product $B$.
