Facile One‐pot Synthesis of Arylsulfonyl‐4H‐pyrans Catalyzed by Ru Loaded Fluorapatite
ChemistrySelect(2020)
摘要
We report a novel ecofriendly cascade reaction for the synthesis of arylsulfonyl-4H-pyran derivatives by a three component fusion reaction of chosen aldehyde, dimedone and phenylsulphonyl acetonitrile at room temperature using ruthenia doped fluorapatite (RuO2/FAp) as recyclable catalyst. Different percentages of RuO2/FAp materials were prepared and characterized by FT-IR, P-XRD, BET, SEM-EDX and TEM analysis. Attractive features of the synthetic approach are operational simplicity, cost-effectiveness, short reaction time and excellent yields. Easily recoverable and reusable catalyst material without any deceptive loss of catalytic activity up to seven cycles is additional benefit.
