  • The effect of <i>ortho</i> and <i>para</i> substituents on the formation of the <i>E</i> and <i>Z</i> isomers of the arylhydrazones obtained from diazonium coupling with methyl 3-aminocrotonate and 3-aminocrotononitrile
    作者:Jason V. Jollimore、Marc Vacheresse、Keith Vaughan、Donald L. Hooper
    DOI:10.1139/v96-029
    日期:1996.2.1

    Reaction of arene diazonium salts with 3-aminocrotononitrile or methyl 3-aminocrotonate affords the 2-aryl-hydrazono-3-oxobutanenitrile (1 or 3 and 3′) or the methyl 2-arylhydrazono-3-oxobutanoate (2 and 2′ or 4 and 4′). A series of these hydrazones has been prepared with a range of electron-withdrawing and -donating substituents in the ortho or para position of the aryl moiety. The hydrazones have been characterized by spectroscopic methods, with emphasis on the 1H NMR spectra, which have been used to determine the configuration of the hydrazones as E or Z or a mixture of the two. The para-substituted hydrazononitriles (1) are formed as a single species, namely the Z isomer, whereas the ortho isomers are formed as a mixture of E and Z configurations (3 and 3′). The hydrazonobutanoates (2 and 2′ or 4 and 4′) are formed as E/Z mixtures regardless of the position of the substituent in the aryl moiety. Complete assignments of all signals in the 1H NMR spectra have been made on the basis of the ability of the various substituents to participate in intramolecular hydrogen bonding and a mechanism is proposed to account for the variations in the proportions of E and Z isomers and the effect of the nature of the substituent on this ratio. 13C NMR spectra of selected hydrazones have been recorded as an aid to structure assignment. Key words: hydrazone, diazonium, NMR spectroscopy, E/Z isomers, crotonic acid derivatives.

    芳香族重氮盐与3-氨基丙烯腈或甲基3-氨基丙烯酸酯反应,得到2-芳基-叠氮基-3-氧代丁腈(1或3和3')或甲基2-芳基叠氮基-3-氧代丁酸酯(2和2'或4和4')。已制备了一系列这些叠氮基化合物,其中芳基部分的邻位或对位具有一系列电子吸引或供给取代基。这些叠氮基化合物已通过光谱方法进行表征,重点放在1H NMR谱上,该谱已用于确定叠氮基的构型为E或Z或两者的混合物。对位取代的叠氮基腈(1)形成为单一种类,即Z异构体,而邻位异构体形成为E和Z构型的混合物(3和3')。叠氮基丁酸酯(2和2'或4和4')无论芳基部分的取代基位置如何,都形成为E/Z混合物。基于各种取代基参与分子内氢键形成的能力,已对1H NMR谱中所有信号进行了完整的指认,并提出了一种机制来解释E和Z异构体的比例变化以及取代基性质对此比例的影响。已记录了选定叠氮基的13C NMR谱,以帮助结构指认。关键词:叠氮基,重氮盐,NMR光谱,E/Z异构体,丙烯酸衍生物。
  • Revisiting the thermal decomposition of five ortho-substituted phenyl azides by calorimetric techniques

    The thermal decomposition (TD) of 2-azidophenylmethanol (1), 2-azidobenzenecarbaldehyde (2), 1-(2-azidophenyl)-1-ethanone (3), (2-azidophenyl)(phenyl)methanone (4) and 1-azido-2-nitrobenzene (5) was analysed by DSC, TG and C80 calorimetric techniques under both oxidative and non-oxidative conditions. The TD of these azides in solution is well known to give the corresponding benzoxazoles, generally
    2-叠氮基苯基甲醇(1),2-叠氮基苯甲醛(2),1-(2-叠氮基苯基)-1-乙酮(3),(2-叠氮基苯基)(苯基)甲酮(4)和1的热分解(TD)通过DSC,TG和C80量热技术在氧化和非氧化条件下分析了-叠氮基-2-硝基苯(5)。众所周知,这些叠氮化物在溶液中的TD可以以高收率得到相应的苯并恶唑,但叠氮化物1除外。当考虑固相和“溶液相” TD反应的结果以及EI-MS实验的结果时,有足够的信息可用来估算叠氮化物的固有分子反应性(MIR)。
