15 صفحه اولConversion of aldoximes into nitriles and amides under mild conditions.
A series of Pd(en)X2 salts were used as catalysts for the conversion of aldoximes into nitriles and amides. Highlights of this protocol include the use of inexpensive polar solvents, including water, and moderate reaction temperatures. A high degree of selectivity in the reaction outcome was observed when using aliphatic vs. aromatic/conjugated aldoximes.

متن کاملUtilization of Various Phosphoryl Halides and Imidazolides for the Conversion of Aldoximes to Nitriles
Although, over the years, considerable interest has been shown in the transformation of aldoximes to nitriles, surprisingly few attempts have been made in utilizing derivatives of phosphorus for this purpose [1-7]. Best results were achieved using aromatic aldoximes, and only seldom were aliphatic aldoximes utilized, affording nitriles in only moderate yields. Recently [8], we reported a novel ...
