A series of 5-aryl-2-furancarbaldehyde 2,6-dialkylphenylhydrazones (Ia - Iv) and dimethylhydrazones (IIa - IIf) as well as related compound benzo[b]furan-2-carbaldehyde dimethylhydrazone (III) were prepared. Compounds Ia - Iv were synthesized by condensing 5-aryl-2-furancarbaldehydes with 2,6-dialkylphenylhydrazines, compounds IIa - IIf were obtained from the same starting compounds and N,N-dimethylhydrazine. The intermediate 5-aryl-2-furancarbaldehydes were prepared by reaction of aryldiazonium chlorides with 2-furancarbaldehyde. The structure of the compounds were proven by 1H, 13C and 15N NMR spectra.
一系列5-芳基-2-呋喃甲醛2,6-二烷基苯基腙(Ia - Iv)和二甲基腙(IIa - IIf)以及相关化合物苯并[b]呋喃-2-甲醛二甲基腙(III)已经制备。化合物Ia - Iv通过5-芳基-2-呋喃甲醛与2,6-二烷基苯基腙缩合合成,化合物IIa - IIf则来自相同起始化合物和N,N-二甲基腙。中间体5-芳基-2-呋喃甲醛通过芳基重氮氯化物与2-呋喃甲醛反应制备。这些化合物的结构通过1H、13C和15N核磁共振谱得到证实。
