Organotrifluoroborate Salts as Complexation Reagents for Synthesizing BODIPY Dyes Containing Both Fluoride and an Organo Substituent at the Boron Center

A convenient procedure for the preparation of functionalized BODIPYs bearing both F and an organo substituent at the boron center, using one-pot reactions between in situ formed dipyrromethenes and organotrifluoroborate salts, has been reported. The complexation reaction utilizes stable and commercial accessible organotrifluoroborate potassium salts and provides a facile access to a variety of novel B-functionalized BODIPYs, which are hard to access through current synthetic methods.
