The participation of nonionic donor-acceptor complex [A] was suggested by the analyses of product isolated in the Friedel–Crafts reaction of m-dichlorobenzene with CH3SO2Cl in the presence of AlCl3. On the basis of these observations a new practical method of methanesulfonylation of deactivated benzenes employing methane-sulfonic anhydride and CF3SO3H was developed.
cathodic H2 productivity. This protocol displays high activity (85–96% yields), catalyst stability (10 cycles), and generality (12 examples) in selective sulfide oxidation. We demonstrate its applicability in the synthesis of four important pharmaceutical related sulfoxide compounds with scalability (up to 1.79 g). X-ray spectroscopy investigations reveal that the CoFe-LDH material evolved into amorphous
