Fe-catalyzed aerobic oxidative esterifications of arylacetonitriles with alcohols, tri alkoxsilanes, silicate esters, or borate esters have been developed. The acyl groups which were in situ generated via chemoselective C(CO)-CN bond cleavage were directly used as electrophiles, leading to corresponding aryl esters in good to excellent yields under molecular oxygen when attacked by alcohols or alcohol
已经开发出铁催化的芳基乙腈与醇,三烷氧基硅烷,硅酸酯或硼酸酯的需氧氧化酯化反应。通过化学选择性的C(CO)-CN键裂解原位产生的酰基直接用作亲电子试剂,当被醇或醇代用品攻击时,在分子氧下产生相应的芳基酯,收率良好至优异,从而得到相应的芳基酯。在该协议中,双氧既充当氧化剂又充当反应物。该反应具有非常宽的底物范围。廉价的原料以及对环境无害且廉价的铁催化剂和理想的氧化剂O 2具有这一转化特性,使其成为一种实用且可持续的提供酯的方法。
