Wang, Shengyu published the artcilePd@CeO2-catalyzed cyanation of aryl iodides with K4Fe(CN)6·3H2O under visible light irradiation, Category: nitriles-buliding-blocks, the main research area is aryl nitrile preparation green chem photochem; potassium ferricyanide aryl iodide cyanation palladium catalyst.
A new protocol based on the combination of the catalyst Pd@CeO2, nontoxic cyanide source K4Fe(CN)6·3H2O, and driving force visible light irradn was developed. The reaction is performed at relatively moderate temperature (55°C) and exhibits good catalytic efficiency of product aryl nitriles RCN (R = Ph, 2-nitrophenyl, thiophen-2-yl, etc.) (yields of 89.4%). Moreover, the catalyst Pd@CeO2 possesses good reusability with a slight loss of photocatalytic activity after five consecutive runs. The reaction system based on the above combination shows a wide range of functional group tolerance under the same conditions. Reaction conditions such as temperature, time, the component of catalyst, and solutions are optimized by studying cyanation of 1-iodo-4-nitrobenzene as model reaction. According to these results, the possible mechanism of Pd@CeO2-catalyzed cyanation of aryl iodides RI under visible light irradiation is proposed based on the influence of visible light on the catalyst and reactant compounds In all, an environmental and economic method for preparation of aryl nitriles from cyanation of aryl iodides based on the goal of green chem. for sustainable development was provided.
