irradiation photocatalytic process. The mild, efficient, and environmentally benign reaction method, involving dynamic reciprocations of cascade pathways, comprises a mixture of a Ru(bpy)3Cl2 photoredox catalyst and DIPIBA or Hünig’s base in CH3CN. Notably, DIPIBA was found to be the best additive for the cross condensation reaction of nitroalkanes with aldehydes. The structures of appropriate products were
使用可见光辐照光催化过程将一系列硝基烷烃有效地转化为烷基硝酮。温和,有效和环境友好的反应方法,涉及级联途径的动态往复运动,包括Ru(bpy)3 Cl 2光氧化还原催化剂和DIPIBA或Hünig碱在CH 3 CN中的混合物。特别地,发现DIPIBA是硝基烷烃与醛的交叉缩合反应的最佳添加剂。通过X射线分析确认适当产物的结构。
