A series of β-formyl-boron-dipyrromethenes (BODIPYs) 2 and β-formyl-aza-BODIPYs 4 were synthesized from tetramethyl-BODIPYs 1 and tetraaryl-aza-BODIPYs 3 respectively via the Vilsmeier-Haack reaction using (COCl)2 and DMF as the precursors efficiently. The Vilsmeier-Haack reaction was carried out smoothly under room temperature or 50℃ for BODIPYs or aza-BODIPYs respectively to give the β-formyl products in good yield. The advantage of this new method is the using of commercially available chemical and the less pollution.

Key words: BODIPY, aza-BODIPY, β-formylation, Vilsmeier-Haack reaction
