    申请人:Boege Nicolas
    公开号:US20130053598A1
    公开(公告)日:2013-02-28
    The invention relates to a method for producing a cross-coupling product of a benzenoid dizonium salt according to the general formula (I), wherein the groups R 1 , R 2 , R 3 , R 4 , and R 5 represent hydrogen, halogen, an alkyl, alkenyl, aryl, alkoxy, aryloxy, nitro, cyano, hydroxy, acetyl, and/or diazo groups independently of each, and X represents BF 4 , Cl, F, SO 3 CH 3 , CO 2 CH 3 , PF 6 , ClO 2 CH 3 , or CIO 4 , comprising the following steps: (a) providing a benzenoid amide, which with the exception of the diazo function has the same substituents R 1 , R 2 , R 3 , R 4 , and R 5 as the benzenoid diazonium salt of the general formula (I), and hydrolytically cleaving the amide to form an amine or providing a corresponding amine, (b) diazotizing the amine thus obtained or provided with a nitrite, and (c) subsequently reacting the benzenoid diazonium salt with a coupling partner in the presence of a catalyst to form a cross-coupling product, wherein the coupling parter is represented by the general formula (II), R 6 , R 7 , and R 8 are the same or different and represent hydrogen, carboxyalkyl groups, carboxyaryl groups, alkyl groups, aryl groups, alkoxy groups, aryloxy groups, wherein the groups can each contain Si, N, S, O, and or halogen atoms, or R 6 and R 7 with the double bound form an aromatic ring, which can be provided with R 8 and one to four further substituents, independently of each other, selected from the group comprising a straight-chain or branched (C 1 -C 6 ) alkyl group, a (C 3 -C 7 ) cycloalkyl group, a straight-chain or branched (C 1 -C 6 ) alkenyl group, a straight-chain or branched (C 1 -C 6 ) alkyoxy group, halogen, the hydroxy group, an amino, di(C 1 -C 6 ) alkylamino, nitro, acetyl, cyan, benzyl, 4-methoxybenzyl, 4-nitrobenzyl, phenyl, and 4-methoxyphenyl group and represents Y=H, —B(OR) 2 , —SnR 3 , —ZnR, —SiR 3 , or Mg (halogen), and wherein at least the steps (b) and (c) are performed without intermediate isolation of an intermediate product. According to said method, cross-couplings can be performed more simply and with improved yield without the hydroxyl group in aromatic reactants containing hydroxyl groups having to be provided with a protective group.

    我们对对羟基和对硝基苯重氮离子的去重氮作用进行了比较研究。-NO2 和 -OH 基团的吸电子和给电子性质强烈决定了两种化合物的反应性,从而对脱重氮反应产生不同的影响。我们在这里描述了在螯合剂二亚乙基三胺五乙酸 (DTPA) 存在下,在中性性介质中对羟基和对硝基苯重氮离子的分解如何遵循不同的模式。对羟基苯重氮的分解速率降低,而对硝基苯重氮离子的分解增强。根据 DTPA 的自由基清除能力,参考对两种苯重氮离子的共同干扰方案讨论了实验数据。恢复 :在实现对羟基和对硝基苯重氮离子去重氮化反应的比较研究中。Les proprieteselectroaffinitaires etelectrorepulsives des groupes -NO 2 et -OH Impactnt fortement la reactivite de ces deux composes et exercent donc

    The dipole moments of α-naphthyl-azo-azulene, β-naphthyl-azo-azulene, phenyl-azo-azulene, and substituted derivatives of the latter have been determined in benzene solution. A discussion of these moments under the assumption that partial moments add vectorially suggests that phenyl-azo-azulene has the trans configuration with the azulene nucleus in the s-trans constellation relative to the azo-bond
