Abstract:Poly(4-vinylpyridine) is reported as a green, commercial available and efficient basic recyclable catalyst for the synthesis of chromene derivatives. This catalyst can be easily recovered by simple filtration and recycled up to 5 consecutive runs without any loss of its efficiency.
Keywords:Poly(4-vinylpyridine)  Chromene  Basic catalyst  &beta  -Naphthol  Malononitrile
