3-benzotriazinones was achieved. With the use of eosin Y as a photoredox catalyst, N,N-diisopropylethylamine as a base, CH3CN–H2O as a solvent and sunlight or a blue LED as a light source, a variety of aryl-phosphonates, aryl-phosphinates, and aryl-phosphine oxides were efficiently prepared. In addition, B2pin2 instead of P-nucleophiles as a radical acceptor was also demonstrated. The key advantages of this
实现了

金属,可见光诱导的
脱氮磷酸化。使用
曙红Y作为光
氧化还原
催化剂,使用N,N-
二异丙基乙胺作为碱,使用CH 3 CN–H 2 O作为溶剂,并使用日光或蓝色LED作为光源,可以使用多种芳基
膦酸酯,芳基-有效地制备了
次膦酸酯和芳基膦
氧化物。另外,用B 2的引脚2代替P-亲核试剂作为自由基受体也被证明。这种新开发的方法的主要优点是反应曲线干净,使用低成本的有机
染料催化剂,能效高,底物范围宽,收率高至优异以及大规模的合成适用性。克级合成的化合物可以在提取后以纯净的形式分离出来,然后重结晶。无需繁琐的色谱纯化。
