A mild catalytic asymmetric direct fluoro-arylation of styrenes has been developed. The palladium-catalyzed three-component coupling of Selectfluor, a styrene and a boronic acid, provides chiral monofluorinated compounds in good yield and in high enantiomeric excess. A mechanism proceeding through a Pd(IV)-fluoride intermediate is proposed for the transformation and synthesis of an sp3 C–F bond.
苯乙烯的温和催化不对称直接氟芳基化已经开发出来。Selectflu、苯乙烯和硼酸的钯催化三组分偶联以良好的收率和高对映体过量提供手性单氟化化合物。提出了一种通过 Pd(IV)-氟化物中间体进行 sp3 C-F 键转化和合成的机制。
