  Exploring the Self-Assembly of Polar Dimeric Capsules Using Molecular Rulers

  摘要：

  A homologous series of N,N,N,N-tetramethylalkyl-N,N-dioxides is used to probe the level of guest induced fit attainable in the assembly of a dimeric capsule based on tetraurea benzyl calix[4]pyrrole components. A sensible enhancement of the capsule's volume was observed in response to guest size for n = 2, 3, and 4. In turn, larger guests adopted folded conformations to adapt to the capsule's dimensions.

  A new system for the selective synthesis of bisdimethylamine derivatives using diols and aqueous dimethylamine as the starting materials was developed. An iridium complex bearing an N-heterocyclic carbene ligand was used as the catalyst, and the reaction proceeded based on the borrowing hydrogen strategy in an aqueous medium under mild conditions. Various bisdimethylamine derivatives were obtained

  We report herein the selective N-methylation of amines and nitroarenes with methanol under basic conditions using carbon-supported Pt nanoparticles (Pt/C) as a heterogeneous catalyst. This method is widely applicable to four types of N-methylation reactions: (1) N,N-dimethylation of aliphatic amines under N2, (2) N-monomethylation of aliphatic amines under 40 bar H2, (3) N-monomethylation of aromatic

  我们在此报告了在碱性条件下使用碳载Pt纳米颗粒（Pt / C）作为非均相催化剂，用甲醇对胺和硝基芳烃进行选择性N-甲基化的过程。该方法广泛适用于四种类型的Ñ -methylation反应：（1）N，N-氮气氛下脂族胺的-dimethylation 2，（2）Ñ -monomethylation下40巴脂族胺为h 2，（3）ñ -monomethylation N 2下的芳香胺的合成；（4）在2 bar H 2下由硝基芳烃和甲醇串联合成N-甲基苯胺。在相同的催化系统下，所有这些反应均显示出适用于多种底物的相应甲胺的收率高，周转率高（TON）和良好的催化剂可重复使用性。机理研究表明，反应是通过借用氢的方法进行的。动力学结果结合密度泛函理论（DFT）计算表明，Pt / C的高性能归因于Pt中等的金属-氢键强度。

  The invention at hand describes Cu-(II)-oxygen adduct complexes, which are stable at room temperature, as well as methods for their production. In this, compounds of the general formula [L-Cu—O—O—Cu-L](BAr 4 ) 2 are concerned. Here, BAr 4 − is a tetraarylborate anion, selected from tetraphenylborate and tetrakis(3,5-trifluoromethyl)phenylborate. L represents a tripodal tetradentate ligand, wherein, each of the four binding sites of the tripodal tetradentate ligand is a nitrogen atom. Each of the three podal ligands is suitable for comprising an aliphatic amine or a nitrogen-containing heteroaromatic compound independently of one another. A bridge of one to four carbon atoms is located between the central nitrogen atom and the nitrogen atom of each of the podal ligands. The Cu-(II)-oxygen adduct complexes according to the present invention are produced, by initially reacting the ligand L with a Cu-(I) salt to [Cu-L]X. Subsequently, the anion X of the Cu-(I) complex [Cu-L]X is replaced with tetraarylborate and the compound [Cu-L]BAr 4 obtained in this way is finally exposed to an oxygen-containing atmosphere. Hereby, [L-Cu—O—O—Cu-L](BAr 4 ) 2 is formed. The Cu-(II)-oxygen adduct complexes are suitable for being used as oxidation catalysts, for example for the oxidation of benzene to phenol or methane to methanol, for the oxidation of hydrogen, aromatic and aliphatic, saturated and unsaturated hydrocarbons, as well as alcohols and amines. Furthermore, detection of the Cu-(II)-oxygen adduct complexes according to the present invention is suitable for being used for the detection of oxygen.

  本发明描述了在室温下稳定的Cu-(II)-氧加合物配合物，以及它们的生产方法。在此，涉及到具有一般式[L-Cu—O—O—Cu-L](BAr4)2的化合物。这里，BAr4−是一种四芳基硼酸盐阴离子，可从四苯基硼酸盐和四(3,5-三氟甲基)苯基硼酸盐中选择。L代表一个三足四齿配体，其中，三足四齿配体的四个结合位点分别是氮原子。每个三足配体适合独立地包括脂肪胺或含氮杂环化合物。在中央氮原子和每个三足配体的氮原子之间有一个由一到四个碳原子组成的桥连接。根据本发明，Cu-(II)-氧加合物配合物是通过首先将配体L与Cu-(I)盐反应形成[Cu-L]X来生产的。随后，Cu-(I)配合物[Cu-L]X的阴离子X被四芳基硼酸盐取代，以此方式获得的化合物[Cu-L]BAr4最终暴露在含氧气氛中。这样，[L-Cu—O—O—Cu-L](BAr4)2就形成了。根据本发明，Cu-(II)-氧加合物配合物适用于用作氧化催化剂，例如用于苯氧化为苯酚或甲烷氧化为甲醇，以及氢氧化、芳香族和脂肪族、饱和和不饱和碳氢化合物、醇类和胺类的氧化。此外，根据本发明，检测Cu-(II)-氧加合物配合物适用于用于检测氧气。

  In a method of synthesizing a silicoaluminophosphate molecular sieve having 90+% CHA framework-type character, a reaction mixture is prepared comprising sources of water, silicon, aluminum, and phosphorus, as well as an organic template. In one aspect, the reaction mixture is heated at more than 10° C./hour to a crystallization temperature and is retained at the crystallization temperature or within the crystallization temperature range for a crystallization time from 16 hours to 350 hours to produce the silicoaluminophosphate molecular sieve. In another aspect, the reaction mixture is heated at less than 10° C./hour to a crystallization temperature from about 150° C. to about 225° C. and is then retained there for less than 10 hours to produce the silicoaluminophosphate molecular sieve. The molecular sieve can then be recovered from the reaction mixture and, preferably, used in a hydrocarbon conversion process, such as oxygenates to olefins.
