基于钯（II）催化的氧化C-H官能化反应，开发了一种用于BODIPY的直接β-选择性苯乙烯化的通用且有效的方法。通过X射线分析证实了高β区域选择性。与起始BODIPY相比，所得染料显示出红移的吸收和发射。这种策略作为快速组装面向多样性的BODIPY文库的后期方法，提供了一种直接的方法来扩展BODIPY系统在2，6位的缀合。
A general and efficient method for direct β‐selective styrylation of BODIPYs has been developed based on Palladium(II)‐catalyzed oxidative C−H functionalization. The high β‐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.
