【 摘 要 】

1,4-Diazabicyclo[2.2.2]octane (DABCO) containing acidic poly(ionic liquid) (DAIL) has been prepared via condensation of 1,4-dichloro butane and DABCO, as an efficient acidic catalyst and has been applied in the one-pot preparation of 2,3-dihydroquinazolin-4(1H)-one derivatives. This catalyst has been characterized by FT-IR and TGA. According to the obtained results including time, yield and recyclability, DAIL could be considered as an efficient catalyst for organic transformations.                KEY WORDS : Poly(ionic liquid), Solvent-free, 2,3-Dihydroquinazolin-4(1H)-ones, DABCO, Multi-component reaction Bull.
