| 描述 |
应用 它也可以在无金属条件下催化可见光引发的4-甲氧基苯乙烯与甲醇的活性阳离子聚合。据Nicewicz实验室报道，这种光催化剂可被蓝色LED激发，在环境温度下可将O-芳基氨基甲酸酯催化为S-芳基氨基甲酸酯，这是对Newman-Kwart重排或钯催化传统上所需的升高反应温度的改进。这种三芳基吡啶鎓盐可用于放大化学或流化反应，可方便地从酚类中获取硫酚。['Nicewicz |
| 英文描述 |
Description Excitable by blue LEDs, this photocatalyst was reported by theNicewiczlaboratory for catalysis ofO-aryl carbamothioates toS-aryl carbamothioates at ambient temperatures, an improvement from the elevated reaction temperatures traditionally needed in the Newman-Kwart rearrangment or palladium catalysis. Effective for scale-up or flow chemistry, this triarylpyrylium salt provides convenient access to thiophenols from phenols.It can also catalyze visible light-initiated, living cationic polymerization of 4-methoxystyrene with methanol under metal-free conditions. |
