The sulphur centered radicals, produced from various organic compounds, in high efficiency by single-electron-transfer (SET) oxidation. These radicals are highly reactive intermediates having various applications in the construction of organosulphur compounds in the field of synthetic organic chemistry. These S-centred radical-mediated organic transformations have been achieved using photoredox catalysts, including organic dyes and transition metal catalysts, as well as in the absence of any catalyst. Compared with previous methods, photoredox catalysis is inexpensive and features the advantages of being environmentally benign, highly efficient and easy to use. This review focuses on recent developments in the photocatalyzed carbon-sulphur bond formation.
通过单电子转移(SET)氧化可高效地从各种有机化合物中产生以硫为中心的自由基。这些自由基是高活性中间体,在合成有机化学领域构建有机硫化合物方面有各种应用。这些以S为中心的自由基介导的有机转化反应已通过光氧化还原催化剂实现,包括有机染料和过渡金属催化剂,并且在没有任何催化剂的情况下也能实现。与以前的方法相比,光氧化还原催化成本低廉,具有环境友好、高效且易于使用的优点。本综述重点关注光催化碳-硫键形成的最新进展。
