Cai, Mingzhong published the artcileRecyclable and Reusable Pd(OAc)2/XPhos-SO3Na/PEG-400/H2O System for Cyanation of Aryl Chlorides with Potassium Ferrocyanide, SDS of cas: 100-70-9, the main research area is reusable palladium acetate XPhos sulfonate catalyst cyanation aryl chloride.
Pd(OAc)2/XPhos-SO3Na in a mixture of poly(ethylene glycol) (PEG-400) and water is shown to be a highly efficient catalyst for the cyanation of aryl chlorides with potassium ferrocyanide. The reaction proceeded smoothly at 100 or 120°C with K2CO3 or KOAc as base, delivering a variety of aromatic nitriles in good to excellent yields. The isolation of the crude products is facilely performed by extraction with cyclohexane and more importantly, both expensive Pd(OAc)2 and XPhos-SO3Na in PEG-400/H2O system could be easily recycled and reused at least six times without any apparent loss of catalytic efficiency.
Catalysis Letters published new progress about Cyanation. 100-70-9 belongs to class nitriles-buliding-blocks, name is Picolinonitrile, and the molecular formula is C6H4N2, SDS of cas: 100-70-9.
