$C_6H_5COOC_2H_5 + 2CH_3MgBr$

Vedclass · Answer

(C) Acetophenone is $C_6H_5COCH_3$.$(A)$ $C_6H_5CHO + CH_3MgBr \rightarrow C_6H_5CH(OH)CH_3$. Oxidation with $Na_2Cr_2O_7/H^+$ gives $C_6H_5COCH_3$ (Acetophenone).$(B)$ $CH_3CHO + C_6H_5MgBr \rightarrow CH_3CH(OH)C_6H_5$. Oxidation with $PCC$ gives $CH_3COC_6H_5$ (Acetophenone).$(C)$ Esters react with $2$ equivalents of Grignard reagent to form tertiary alcohols. $C_6H_5COOC_2H_5 + 2CH_3MgBr \rightarrow C_6H_5C(OH)(CH_3)_2$. This does not give acetophenone.$(D)$ Acid chlorides react with organocadmium reagents (formed in situ from $2RMgX + CdCl_2$) to give ketones. $2C_6H_5COCl + (CH_3)_2Cd \rightarrow 2C_6H_5COCH_3$. This gives acetophenone.

Which of the following conditions or reaction sequences will $NOT$ give acetophenone as the major product?
