A cobalt-catalyzed cascadereaction of N-aryl thiocarbamoylfluorides and water has been developed, providing access to 3-alkyl-2(3H)-benzothiazolones in 48–83% yields. This protocol for 3-alkyl-2(3H)-benzothiazolones precludes bad-smell and toxic reagents. Mechanistic studies suggest that the transformation proceeds through hydrolysis followed by dehydrogenative coupling to form C−S bond involving
