(BODIPY) derivatives were synthesized through Pd(II)-catalyzed regioselective and stereoselective oxidative C–H olefination in one step. The 2-alkenyl BODIPY derivative further reacted with various amines regioselectively at the 5-position through direct oxidative nucleophilic substitution. The photophysical properties of the 2-alkenyl- and 2,6-dialkenyl-substituted BODIPYs were investigated, which showed
通过Pd(II)催化的区域选择性和立体选择性氧化C–H烯化反应,一步合成了一系列2-烯基和2,6-二烯基硼二吡咯亚甲基(BODIPY)衍生物。通过直接氧化亲核取代,2-烯基BODIPY衍生物进一步在5-位与各种胺发生区域选择性反应。研究了2-烯基和2,6-二烯基取代的BODIPY的光物理性质,在荧光生物成像中显示出巨大的潜力。
