Gold nanoparticles were decorated onto sulfonated three‐dimensional graphene (3DG‐SO3H) through spontaneous chemical reduction of HAuCl4 by 3DG‐SO3H. This nanocomposite exhibited excellent catalytic activity for the synthesis of symmetric biaryls via the Ullmann homocoupling of aryl iodides in an aqueous medium. Additionally, this nanocomposite was used as a catalyst for the reduction of p‐nitrophenol...
We have been studying the development of new asymmetric two-center catalysis using rare earth alkoxides and bifunctional sugar and related ligands. In The Fourth International Conference on Multi-Component Reactions and Related Chemistry (MCR 2009), new catalytic asymmetric reactions using catalysts 1 and 2 and catalytic asymmetric syntheses of ranirestat 3 and tamiflu 4 will be presented.
4-Substituted-spiro-1,2-dihydroquinazolines and related compounds were synthesized by direct reaction of 2-aminobenzophenones, isatin, or 1,2-diketone derivatives and ammonium acetate in the presence of dual role catalyst-solvent ionic liquid, [Hmim]TFA. Excellent conversion of starting materials was achieved to the desired 1,2-dihydroquinazoline products.
