摘要：

A general and efficient method for direct beta-selective styrylation of BODIPYs has been developed based on Palladium(II)-catalyzed oxidative C-H functionalization. The high beta-regioselectivity was confirmed by X-ray analysis. The resulting dyes showed bathochromically shifted absorption and emission compared to that of the starting BODIPYs. This strategy, as a late-stage approach to rapidly assemble a diversity-oriented BODIPY library, provides a straightforward way to extend the conjugation of the BODIPY system at 2,6-positions.
