Direct oxidative nucleophilic substitution of the 3-hydrogen of BODIPY dyes by pyrrole has been developed under reflux condition under oxygen, from which a series of pyrrolyldipyrrinato BF(2) complexes 1a-h, as extended BODIPYs, have been synthesized. Most of these BODIPYs show strong fluorescence emissions at wavelengths over 600 nm in six solvents of different polarity. Removal of the BF(2) group
BODIPY染料的3-氢在氧的回流条件下直接氧化亲核取代反应已在氧气的回流条件下发展,由此合成了一系列吡咯基二吡咯烷酮BF(2)络合物1a-h,作为扩展的BODIPYs。这些BODIPY中的大多数在六种不同极性的溶剂中均在600 nm以上的波长处显示出强荧光发射。从BODIPY 1e中除去BF(2)基团可以高产率获得相应的游离基吡咯烷基二吡咯啉7,作为天然产物prodigiosin的类似物。
