摘　　要：Two new aromatic β-diketones,1-phenyl-3-（6methoxy-1-naphthyl）propane-1,3-dione（a） and 1-（4-tert-butylphenyl）-3-（6-methoxy-1-naphthyl）propane-1,3-dione（b） were synthesized from aromatic ketone and ester by classical Claisen condensation using NaNH2 as strong base.And their structures were determined by means of UV,IR,1H NMR spectra and elemental analysis.The results show that two β-diketone compounds have strong ultraviolet absorption and exist in the enol form in chloroform solvent.Two new aromatic β-diketones,1-phenyl-3-（6-methoxy-1-naphthyl）propane-1,3-dione （a） and 1-（4-tert-butylphe- nyl）-3-（6-methoxy-1-naphthyl）propane-1,3-dione （b） were synthesized from aromatic ketone and ester by classical Claisen condensation using NaNH2 as strong base. Aad their structures were determined by means of UV,IR,^1H NMR spectra and elemental analysis. The results show that two β-diketone compounds have strong ultraviolet absorption and exist in the enol form in chloroform solvent.
