| Abstract: | Symmetrical N,N′-alkylidene
bisamides have been synthesized in excellent yield by the condensation of
aromatic ′aldehydes and amides in the presence of phosphotungstic acid as a
catalyst under thermal and neat microwave irradiation conditions. It is the
first successful report of phosphotungstic acid being used as Brønsted acid
catalyst for the preparation of symmetrical N,N′-alkylidene
bisamides. The remarkable advantages offered by this method are green catalyst,
mild reaction conditions, simple procedures and excellent yield of product. |
