The relative reactivity of photosolvolysis of a number of substituted benzyl acetates is in the order ortho > meta > para, these substitutent effects being apparently additive, as suggested by the relative reactivity of photomethanolysis of several dimethoxy-substituted benzylalcohols.

The liquid-phase oxidation of methylbenzenes catalyzed by a catalyst system composed of cobalt(II) and copper(II) acetates and sodium bromide was carried out in acetic acid at 150 °C. The corresponding benzyl acetates and benzaldehydes were obtained in high selectivities in most cases. A nuclear-brominated product, i.e., 3-bromo-4-methoxytoluene was also obtained in the oxidation of p-methoxytoluene
由乙酸钴(II)和乙酸铜(II)和溴化钠组成的催化剂体系催化甲基苯的液相氧化,在乙酸中于 150 °C 下进行。在大多数情况下,以高选择性获得相应的乙酸苄酯和苯甲醛。在对甲氧基甲苯的氧化中也得到核溴化产物,即3-溴-4-甲氧基甲苯,其具有两个不同的反应位点,即供电子甲氧基取代基的邻位和苄基位。然而,在催化剂体系中溴离子取代乙酸根离子对侧链氧化产物具有令人满意的选择性。在对二甲苯氧化中,还得到了α,α'-二乙酰氧基-对二甲苯和对(乙酰氧基甲基)苯甲酸,以及对甲基乙酸苄酯,虽然他们的金额很小。还进行了多甲基苯的氧化。

We developed a ruthenium-catalyzed reductive estersynthesisfrom aldehydes or ketones and carboxylic acids using carbon monoxide as a deoxygenative agent. Multiple factors influencing the outcome of the reaction were investigated. Best results were obtained for commercially available and inexpensive benzene ruthenium chloride; as low as 0.5 mol % of the catalyst is sufficient for efficient reaction

A rhodium‐catalyzed reductiveesterification of carboxylicacids with carbonyl compounds was developed. This protocol fits a variety of carboxylicacids and aldehydes, opening the short way from industrial bulk compounds to valuable esters.
