Aliphatic compounds substituted with medicinally important trifluoromethylthio (SCF3) and trifluoromethylselenyl (SeCF3) groups were synthesized directly from alcohols by using the new benzothiazolium salts BT‐SCF3 and BT‐SeCF3. These bench‐stable fluorine‐containing reagents are facile to use and can be prepared in two steps from non‐fluorinatedheteroaromatic starting materials. The metal‐free d

In this work, 27 novel hybrid derivatives containing diverse substituents with chalcogen atoms (selenium or sulfur) and several active heterocyclicscaffolds have been synthesized. Compounds were tested against two human cancer cells lines (MCF7 and PC-3) and a normal human mammary epithelial cell line (184B5) in order to determine their activity and selectivity against malignant cells. Ten compounds
