The combination of catalytic aqueous hydrochloric acid (HCl) and N-bromosuccinimide (NBS) generated electrophilic bromine monochloride (BrCl), which readily induced spiroannulation of 2-alkynolyl anilides (n = 1-3) to form gem-dibromospirocyclic benzo[d][

An ortho-amination, ipso-C-H arylation mediated by palladium/norbornene cooperative catalysis is reported. This reaction proceeds through a sequential intermolecular C-N bond formation process followed by intramolecular C-H activation of a tethered arene. The products, aminated phenanthridinones, were generated in moderate to good yields. This method is also applicable to the formation of dibenzazepinones.
Iodine-catalyzed, stereo- and regioselective synthesis of 4-arylidine-4H-benzo[d][1,3]oxazines and their applications for the synthesis of quinazoline 3-oxides

4-Benzylidene-2-aryl-4H-benzo[d][1,3] oxazines have been synthesized with high stereoselectivity and regioselectivities from 2-alkynylbenzamides in the presence of a catalytic amount of I2. In the reaction mechanism, iodine plays a key role in
