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.
