Methyl benzoate bromide

Triphenylcarbinol has been obtained by the reaction between phenylmagnesium bromide and benzophenone,1 methyl benzoate, or phosgene 8 by action of phenylsodium upon benzophenone, benzoyl chloride, ethyl chlorocarbonate, or ethyl benzoate 4 by hydrolysis of triphenylchloromethane 5 and by oxidation of tri-phenylmethane.6...

The Grignard reagent—magnesium phenyl bromide—is prepared as described in Preparation 21 from 1-2 gms. (1 mol.) of dry magnesium and 8 gms. (1 mol.) of dry bromobenzene. 6-8 gms. (1 mol.) of dry methyl benzoate dissolved in 25 gms. of sodium-dried ether are added to the cold solution, slowly and with constant shaking. The liquid is then heated on a water bath until no further change takes place. Ice and dilute sulphuric acid are added to the cold reaction mixture, which, when the precipitate has dissolved, is steam distilled. The triphenyl carbinol which remains is recrystallised from benzene. 

Bromination of methyl benzoate requires more vigorous conditions catalysis by iron(III) bromide is required for bromination of deactivated aromatic rings.

In general, the excited radicals shown have been found to possess enhanced donor/acceptor properties, especially in interactions with such quenchers as oxygen, dienes, amines, and halides. To date, the most well-characterized intermolecular processes are charge (electron) transfer reactions between excited diphenyl-methyl radicals and electron donors and acceptors. Thus, excited 132 reacts with methyl benzoates and benzyl bromides (Schemes 23 and 24) with rates that increase with the increasing electron withdrawing ability of substituents on the... 

Consider an example using an ester. When an excess of ethylmagnesium bromide is added to methyl benzoate, the first equivalent adds and methoxide is expelled, giving propiophenone. Addition of a second equivalent, followed by protonation, gives a tertiary alcohol 3-phenylpentan-3-ol.

Anionic micellar systems were found to increase the rate of the acid catalyzed hydrolysis of acetylsalicylic acid (Nogami et al., 1962), methantheline bromide (Nogami and Awazu, 1962), n-butyl acetate, t-butyl acetate, ethyl p-aminobenzoate, and ethyl o-aminobenzoate (Sakurada et al., 1967), but decreased that of methyl benzoate slightly (Sakurada et al., 1967). The acid catalyzed hydrolysis of anionic amphi-philes also generally tend to be accelerated by micellization (Table 5). The rates of the acid catalyzed hydrolyses of sodium sulfoethyl do-decanoate, sodium undecanoate, and sodium sulfobutyl caprylate are significantly greater in micellar than in non-micellar solutions while that of sodium dodecyl sulfoacetate is unaffected by micelle formation (Meguro and Hikota, 1968). 

Mix 5 g (0.037 mole) of methyl benzoate and 15 mL of absolute ether in a separatory funnel, cool the flask containing phenylmagnesium bromide solution briefly in an ice bath, remove the drying tube, and insert the stem of the separatory funnel into the top of the condenser. Run in the methyl benzoate solution slowly with only such cooling as is required to control the mildly exothermic reaction, which affords an intermediate addition compound that separates as a white solid. Replace the calcium chloride tube, swirl the flask until it is at room temperature and the reaction has subsided.
