photoredox catalysis, we have now achieved the first example of catalytic dehydrogenative coupling of phosphines and thiophenols that proceeds at room temperature. Key to our success is the use of benzaldehyde as a soft oxidant, which avoids the issue of phosphine oxidation. Furthermore, we observed the unexpected dealkylative coupling of secondary and tertiary alkylphosphine with thiophenols.
在此,通过应用可见光光氧化还原催化,我们现在已经获得了在室温下进行的膦和硫酚的催化脱氢偶联的第一个实例。我们成功的关键是使用苯甲醛作为软氧化剂,避免了膦氧化的问题。此外,我们观察到了仲和叔烷基膦与硫酚的意外脱烷基偶联。
