Reactions of thiocarbonyl fluoride derivedfrom cheap, readily available, and widely used CF3SiMe3, elemental sulfur, and KF with secondaryamines and primaryamines at room temperature in THF provided a wide variety of thiocarbamoyl fluorides and isothiocyanates in moderate to excellent yields, respectively. The two reactions show broad substrate scope and good functional group tolerance. Moreover

many types of biological activities and have recently been reported to show substantial antitumor activity in vitro and/or in vivo. There are a variety of mechanisms for the anticancer activity and the most prominent of these is through the inhibition of carbonic anhydrase isozymes. The present work reports the synthesis of some novel quinoline and pyrimido[4,5-b]quinolinederivatives bearing a substituted
