Microwave-assisted reduction of F-BODIPYs and dipyrrins to generate dipyrromethanes

  Introduction            Dipyrrins present a useful ligand scaffold, with significant interest being devoted to dipyrrinato complexes of transition metals and boron. (1,2) There are limited reports

Article Description

"Chemical eqation presented" 4,4-Difluoro-4-bora-3a,4a-diaza-s- indacenes (F-BODIPYs) have been deprotected to give the corresponding free-base dipyrrins by heating a solution of the F-BODIPY in tert-butanol under 600 W of microwave irradiation in the presence of 6 equiv of potassium tert-butoxide for 40 min at 92 C. Investigations of BODIPY modification at the meso position have also been undertaken and a meso-butyl product has been isolated. © 2010 American Chemical Society.
