  摘要：

  Abstractmagnified imageThe selective fluorination of diamantane, triamantane, [121]tetramantane, and [1(2,3)4]pentamantane bromides and alcohols was achieved by using the fluorinating agents silver fluoride (AgF) and diethylaminosulfur trifluoride (DAST). Various mono‐, di‐, tri‐ and even tetrafluorinated diamondoid derivatives were prepared and characterized. We were also able to prepare the amino fluoro and the fluoro alcohol derivatives of diamantane from the corresponding monoprotected diamondoid diols. These reactions can be carried out in a highly selective manner and proceed without isomerizations. The fluorinated, unequally disubstituted derivatives are valuable compounds for the exploration of electronic, pharmacological, and material properties of functionalized diamondoids.

  摘要：

  使用亲电试剂（Br2、硝酸）对金刚烷、三金刚烷和四金刚烷进行官能化会产生各种顶端和中间双取代产物，这些产物被单独分离和表征。通过酸催化异构化以高制备产率获得了非常理想的和否则无法获得的热力学更稳定的顶端双衍生物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

  (desymmetrization) of diamondoid, benzylic, and ethynyl diols has been achieved using fluorinated alcohols such as 2,2,2-trifluoroethanol (TFE) under acidic conditions. This practical acid-catalyzed S(N)1 reaction opens the door for the synthesis of novel bifunctional diamondoids. With diamantane as an example, we show that the resulting monoethers can be used to prepare selectively, for instance, amino

  The selective functionalizations of the fundamental hydrogen-terminated nanodiamonds triamantane 1, as well as the most symmetrical representative of the tetramantanes (C2h-[121]tetramantane 2) were elaborated. Electrophilic reagents (Br2, HNO3) predominantly attack the medial C−H positions of the cages; bromination of 2 gave the medial 2-bromo derivative almost exclusively. Highly selective apical

  The invention at hand describes functionalized diols of diamondoids, in which one of the two hydroxy groups is masked by a protective group, as well as methods for producing these functionalized diols. The protective group is a group —CHR 1 R 2 , wherein R 1 and R 2 stand for alkyl groups and the protective group comprises at least one halogen atom. The monoethers of the diamondoid diols according to the present invention are produced by reacting the diamondoid diol with a halogenated alcohol CHOHR 1 R 2 in the presence of a catalyst acid. The monoetherified diols allow for the targeted production of derivatives of diamondoids, for example, of the corresponding aminoalcohols and aminocarboxylic acids. For that purpose, the diamondoid monoether is reacted in a first step with a halogen nitrile in a Ritter reaction to the corresponding monoether amide. From this monoether amide, the corresponding aminoalcohol can be produced by reacting the protective group —CHR 1 R 2 first with trifluoroacetic acid to the alkanoyloxy group and by subsequently obtaining the aminoalcohol by reaction with thiourea, ethanol and glacial acetic acid. The aminoalcohol can be reacted with a sulfuric acid/formic acid or oleum/formic acid to the corresponding aminocarboxylic acid. The amino, hydroxy and carboxylic groups of the diamondoids can be converted into many other functional groups.

  这项发明描述了钻石烷的官能化二元醇，其中两个羟基中的一个被保护基掩盖，以及制备这些官能化二元醇的方法。保护基是一个基团—CHR1R2，其中R1和R2代表烷基，保护基包含至少一个卤素原子。根据本发明，钻石烷二元醇的单醚是通过在催化酸的存在下将钻石烷二元醇与卤代醇CHOHR1R2反应而制备的。单醚化的二元醇允许有针对性地生产钻石烷的衍生物，例如相应的氨基醇和氨基羧酸。为此，首先将钻石烷单醚与卤代腈在里特反应中反应得到相应的单醚酰胺。从这个单醚酰胺中，通过将保护基—CHR1R2先与三氟乙酸反应成烷酰氧基，然后通过与硫脲、乙醇和冰醋酸反应获得氨基醇。氨基醇可以与硫酸/甲酸或油酸/甲酸反应成相应的氨基羧酸。钻石烷的氨基、羟基和羧基可以转化为许多其他官能团。
