A new dimeric ortho-palladated complex of 2-methoxyphenethylamine was synthesized and characterized and its application as a cyanation catalyst was investigated. The main advantages of this catalyst are its easy preparation, handling, stability, and moisture insensitivity. Thus, [Pd{C 6 H 3 (CH 2 CH 2 NH 2 )-4-OMe-5-j 2 -C,N}(l-Br)] 2 showed excellent catalytic activity for the cyanation of aryl iodides and bromides with K 4 [Fe(CN) 6 ], in DMF in the presence of K 2 CO 3 under microwave irradiation and conventional heating at 130°C to give the desired cyanoarene products in good to high yields. The less reactive aryl chlorides also react with K 4 [Fe(CN) 6 ] to give moderate yields of the aromatic nitriles. The effects of various parameters such as solvent, base, and amount of catalyst were studied. The reaction is suitable for a wide variety of substituted aryl halides with different electronic properties. Application of microwave irradiation improved the yields of the reactions and reduced the reaction times from hours to minutes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
