generality of the palladium-catalyzed C–C coupling Negishi reaction when applied to haloBODIPYs is demonstrated on the basis of selected starting BODIPYs, including polyhalogenated and/or asymmetrical systems, and organozinc reagents. This reaction is an interesting synthetic tool in BODIPY chemistry, mainly because it allows a valuable regioselective postfunctionalization of BODIPY chromophores with
当应用于卤代BODIPYs时,钯催化的CC偶联Negishi反应的普遍性是根据选定的起始BODIPYs证明的,包括多卤代和/或不对称体系,以及有机锌试剂。该反应是BODIPY化学中一个有趣的合成工具,主要是因为它允许对具有不同官能团的BODIPY生色团进行有价值的区域选择性后官能化。以此方式,现在可以制成难以通过其他程序获得的功能模式(例如,涉及卤代位置的不对称功能化的BODIPY)。区域选择性是通过控制反应条件来实现的,并且基于几乎普遍的反应性偏好以及所涉及卤素的性质及其位置。
