A novel CuO-catalyzed coupling reaction of arylhydrazines with trialkylphosphites to afford arylphosphonates is described. The reaction proceeded at 80 °C in air without external reductants, oxidants, and ligands.
construction of an aromatic-phosphorus (Ar-P) bond under visiblelight irradiation using Cu2O/TiO2 nanoparticles as inexpensive and available photocatalysts. This protocol is a simple system without the use of any base, ligand, oxidant, or special conditions. This is the first report for the synthesis of arylphosphonates from arylhydrazines in visiblelight irradiation.
已经开发出一种新颖有效的方法,用于在可见光照射下使用Cu 2 O / TiO 2纳米粒子作为廉价和可用的光催化剂来构建芳族磷(Ar-P)键。该方案是一个简单的系统,无需使用任何碱,配体,氧化剂或特殊条件。这是在可见光照射下由芳基肼合成芳基膦酸酯的第一份报告。
