The direct arylation on the thienyl groups of a diarylethene with various aryl iodides efficiently provided arylated dithienylethenes under palladium catalysis. Unsymmetrically substituted dithienylethenes were also synthesized by this protocol. This procedure allows a rapid access to a variety of aryl-substituted dithienylethenes from a single substrate of a simple dithienylethene.
在钯催化下,二芳基乙烯的噻吩基与各种芳基碘化物的直接芳基化有效地提供了芳基化的二噻吩基乙烯。该协议还合成了不对称取代的二噻吩基乙烯。该方法允许从简单的二噻吩基乙烯的单个底物快速获得各种芳基取代的二噻吩基乙烯。
