摘要：
A facile method for the synthesis of benzo[f]chromene derivatives is reported. The procedure involves a novel three-component reaction of 1-naphthol or 2-naphthol, acetophenone derivatives and triethyl orthobenzoate in the presence of silica supported ionic liquid [pmim]HSO4 (SiO2) [silica supported 1-methyl-3-(triethoxysilylpropyl) imidazolium hydrogensulfate] as an efficient catalyst.
