Vedclass · Answer

(A) The reaction involves the conjugate addition (also known as $1,4$-addition) of an organometallic reagent to an $\alpha,\beta$-unsaturated carbonyl compound.In the presence of copper salts (like $CuCl$),the Grignard reagent $(PhMgBr)$ forms an organocopper species $(PhCu)$,which acts as a 'soft' nucleophile.Soft nucleophiles prefer to attack the $\beta$-carbon of the $\alpha,\beta$-unsaturated system rather than the carbonyl carbon (which is a 'hard' electrophilic site).Therefore,the phenyl group $(Ph)$ adds to the $\beta$-position of the cyclohexenone ring,followed by protonation $(H^+)$ of the resulting enolate to yield $2$-phenylcyclohexanone.
