Conversion of F-BODIPYs to Cl-BODIPYs: enhancing the reactivity of F-BODIPYs.
A new method for the synthesis of Cl-BODIPYs from F-BODIPYs is reported, merely requiring treatment of the F-BODIPY with boron trichloride. Cl-BODIPYs are exploited as synthetic intermediates generated in situ for the overall conversion of F-BODIPYs to O- and C-BODIPYs in high overall yields using a mild one-pot procedure. This route enables F-BODIPYs to be transformed into derivatives that are...
متن کاملCl-BODIPYs: a BODIPY class enabling facile B-substitution.
Cl-BODIPYs, synthesized in high yields from dipyrrins under air- and moisture-free conditions, are extremely facile to substitution at boron compared to their corresponding F-BODIPYs, opening up a new route to BODIPYs functionalized at boron.
متن کاملActivation and deprotection of F-BODIPYs using boron trihalides.
The activation of F-BODIPYs with boron trihalides, followed by treatment with a nucleophile, effects facile substitution at boron; using water as the nucleophile promotes deprotective removal of the -BF2 moiety and thereby production of the corresponding parent dipyrrin salt in quantitative yield under extremely mild conditions.
