Abstract
Efficient racemization of enantiomerically pure methyl aryl sulfoxides was obtained by N-methylquinolinium tetrafluoborate (NMQ+) sensitized photolysis and by one-electron oxidation catalyzed by tris(2,2'-bipyridyl)ruthenium(III) hexafluorophosphate.
摘要
通过四氟硼酸N-甲基喹啉鎓（NMQ +）敏化光解以及由六氟磷酸三（2,2'-联吡啶）钌（III）催化的单电子氧化，实现了对映体纯的芳基甲基亚砜的高效外消旋化。
