実験手順

Five g of 7-methoxybenzotelluropyrone was added to 20 ml of freshly distilled ethyl fluorosulfonate. The resulting mixture was stirred under nitrogen at 60° C. for 10 minutes. Two hundred ml of ether was added precipitating a red solid. The product was collected by filtration and recrystallized from acetonitrile to give 6.0 g (87%) of a red solid.
