    β-二酮和水合肼反应合成了标题化合物,采用元素分析、IR、~1HNMR和ESI-MS对其结构进行了鉴定和分析.由于这种1H-吡唑化合物能形成N-H…N分子间的氢键,因而在ESI-MS图上出现很强的二聚体离子峰[2M]~+.

    A new 1H-pyrazole compound: 3(5)-(4-(benzyloxy) phenyl)-5 (3)-(furan-2-yl)-lH-pyrazole (3) was synthesized from β-diketone and hydrazine hydrate. The composition and structure of the new compound were characterized by means of el-emental analysis, IR, ~1HNMR and ESI-MS. A strong peak of dimeric ions [2M]~+ was observed in the ESI-MS spectra attribut-ed to the formation of dimers by intermolecular N H…N hydro-gen bonds.
