氟硼吡咯和氮杂氟硼吡咯分别与草酰氯在N,N-二甲基甲酰胺溶液中发生Vilsmeier-Haack反应, 生成相应的β-甲酰氟硼吡咯和β-甲酰氮杂氟硼吡咯. 该反应分别在室温和50℃搅拌条件下顺利实现, 并对氟硼吡咯和氮杂氟硼吡咯两种底物都具有较高产率. 此外, 该反应具有原料易得、低污染的优点.

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.
