Benzyl acetate benzoate

Mix 31 g. (29-5 ml.) of benzyl alcohol (Section IV, 123 and Section IV,200) and 45 g. (43 ml.) of glacial acetic acid in a 500 ml. round-bottomed flask introduce 1 ml. of concentrated sulphuric acid and a few fragments of porous pot. Attach a reflux condenser to the flask and boil the mixture gently for 9 hours. Pour the reaction mixture into about 200 ml. of water contained in a separatory funnel, add 10 ml. of carbon tetrachloride (to eliminate emulsion formation owing to the slight difference in density of the ester and water, compare Methyl Benzoate, Section IV,176) and shake. Separate the lower layer (solution of benzyl acetate in carbon tetrachloride) and discard the upper aqueous layer. Return the lower layer to the funnel, and wash it successively with water, concentrated sodium bicarbonate solution (until effervescence ceases) and water. Dry over 5 g. of anhydrous magnesium sulphate, and distil under normal pressure (Fig. II, 13, 2) with the aid of an air bath (Fig. II, 5, 3). Collect the benzyl acetate a (colourless liquid) at 213-215°. The yield is 16 g. 

The THP ether can be converted directly to an acetate by refluxing in AcOH/AcCl (91 % yield). These conditions would probably convert other related acetals to acetates as well. The THP group can also be converted through the 0-SnBu3 to benzyl, MEM, benzoate, and tosylate groups. ... 

Methyl benzoata, tnelbvl salicylate, benzyl acetate, benzyl benzoate, and Iren benzyl alcohol are present in small amounts, as well as methyl anthraniJale and oreosol in Iraoea. Tliicod has also recently identified lormic acid, and aatrol or iso-saliol. 

One consequence of the shift from grassland to shrubland is the potential for significant increases in volatile hydrocarbons added to the atmosphere. The leaves of creosotebush, Larrea tridentata, yielded 0.1 to 0.2 percent of a complex mixture of volatile compounds. That mixture contains several hundred compounds of which 100 accounted for more than 90% of the total volatiles (23). The volatiles that were identified included four monoterpene hydrocarbons, four oxygenated monoterpenes, six sesquiterpene hydrocarbons, eight aromatics like benzyl acetate and ethyl benzoate, plus... 

These photoinduced reactions proceed in fair to good yields (50-80%) and tolerate a variety of protecting groups at C-6, e.g., acetate, benzoate, methyl, and benzyl.

Reduction of derivatives of ally lie alcohols. Nickel boride can effect reduction of allylic alcohols to alkenes, but yields are generally improved by reduction of the acetates, benzoates, or trifluoroacetates.1 Reduction of allylic benzyl ethers to alkenes is effected in higher yield with Raney nickel. Methyl ethers are not reduced by either reagent. The trimethylsilyl ethers of allylic alcohols are reduced to alkenes by nickel boride in diglyme.2...

The conversion of steroidal ketoximes and the derived oxime acetates, benzoates and methyl and benzyl ethers into enamides was described by Barton and coworkers621,622. For example, the oxime of 5-a-cholestan-3-one (147) forms with acetic anhydride in pyridine the enamide 148 which, under the reaction conditions, is acetylated on nitrogen to form the enimide 149. Chromatography on alumina cleaves the enimide to the enamide. 

A particularly illuminating study involving isotopic substitution concerns the reaction of N-tritiated diethylamine with methyl benzoate (Kitamura et al., 1977). It was found that tritium was preferentially substituted into the p-position. There was also substantial substitution in the o-position but more surprising, the methyl group of the ester was labelled. It was proposed that reaction occurs as shown in Scheme 7 via radical ions [68] and [69]. 4-Cyano-benzyl-acetate, on irradiation in the presence of triethylamine is cleaved to give 4-cyanotoluene and 4,4 -dicyanobibenzyl (Ohashi et al., 1977d). When O-deuteriated methanol was used as solvent, deuterium was incorporated...
