An efficient transformation of the sulfur atoms to the sulfonyl group in a range of thienopyrroles was achieved by using the HOF·CH3CN complex. Mild conditions, high yields, and easy purification are the main features of this novel route. Most new materials exhibit considerable red-shift absorptions in the UV/visible range relative to the parent compounds.
通过使用HOF·CH 3 CN络合物,可以在一定范围的噻吩并吡咯中将硫原子有效转化为磺酰基。温和的条件,高收率和易于纯化是该新途径的主要特征。相对于母体化合物,大多数新材料在UV /可见光范围内均显示出可观的红移吸收。
