Vedclass · Answer

(C) Dimethyl carbonate $(CH_3OCOOCH_3)$ reacts with an excess of phenylmagnesium bromide $(PhMgBr)$ to produce triphenylmethanol $(Ph_3COH)$. The reaction occurs in three steps:$1.$ Nucleophilic acyl substitution of the first methoxy group to form methyl benzoate: $CH_3OCOOCH_3 + PhMgBr \rightarrow PhCOOCH_3 + CH_3OMgBr$$2.$ Nucleophilic acyl substitution of the second methoxy group to form benzophenone: $PhCOOCH_3 + PhMgBr \rightarrow PhCOPh + CH_3OMgBr$$3.$ Nucleophilic addition to the ketone followed by hydrolysis to form triphenylmethanol: $PhCOPh + PhMgBr$ $\rightarrow Ph_3COMgBr$ $\xrightarrow{H_3O^{+}} Ph_3COH$.

What product would you expect to obtain from a Grignard reaction when an excess of phenylmagnesium bromide reacts with dimethyl carbonate $CH_3OCOOCH_3$?
