Thiomethylation, Nitro Reduction and Tandem Reduction/SMe Insertion of Nitrogen Heterocycles Using BF₃⦁SMe₂

Herein, a general, solvent-free and straightforward thiomethylation of electron deficient heterocycles using BF3⦁SMe2 as a dual thiomethyl source and Lewis acidic activator is presented. A range of ...
