The aerobic oxidation is an attractive approach toward environmentally benign synthesis of fine chemicals. In addition, dye-sensitized semiconductors are underdeveloped photocatalysts for selective organic synthesis. With the aid of catalytic eosin Y-sensitized titanium dioxide, we have developed efficient aerobic photooxidation of benzyl ethers to benzoates, featuring low cost, high atom economy,
有氧氧化是一种在环境上良性合成精细化学品的有吸引力的方法。另外,染料敏化半导体是用于选择性有机合成的未开发的光催化剂。借助于催化曙红Y敏化的二氧化钛,我们开发了苄基醚有效的好氧光氧化为苯甲酸酯的方法,具有低成本,高原子经济性,广泛的底物范围和用户友好的设置的特点。此外,初步的机理研究表明,反应途径可能需要通过可分离的过氧化物中间体进行光诱导的基于自由基的两步过程。
