A family of quinoline–platinum(II) complexes as efficient photocatalysts is presented. Their key characteristic is their easy preparation by coordination of the readily available 8-hydroxy- or 8-thio-quinoline ligands, which are well known for their strong chelating ability to different metal ions. In the different photochemical transformations investigated, such as cross-dehydrogenative coupling,
介绍了一种喹啉-铂(II)配合物作为有效的光催化剂。它们的关键特征是通过容易获得的8-羟基-或8-硫代喹啉配体的配位可轻松制备,这些配体因其对不同金属离子的强螯合能力而闻名。在研究的不同光化学转化中,例如交叉脱氢偶联,芳基硼酸的氧化和醛的不对称烷基化,8-巯基喹啉-Pt(II)络合物被证明是最通用的催化剂。此外,猝灭实验表明,与文献报道的相关方法相反,这些配合物在所有研究的转化中均遵循氧化猝灭机理。除了,
