  N , N -1,2-Benzenedisulfonylimide, a new cyclic leaving group for the stereoselective nucleophilic substitution of amines

  摘要：

  We hereby report the preparation and nucleophilic substitutions of the N,N-1,2-benzenedisulfonylimide derivatives la and 2a of the chiral amines 1 and 2. The nucleophilic attack of KNO2 afforded the respective alcohols 3 and 4 with 84-90% inversion of configuration. Nucleophilic attack by the azide ion afforded the azide products 5 and 6 which were reduced to the corresponding inverted amines 1 and 2 (94-98.5% inversion). The improved leaving group ability of the N,N-1,2-benzenedisulfonylimides compared with previously reported N,N-disulfonylimides is discussed. Chiral GLC analysis of all products is summarized and the alternative chiral analysis of product 3 by C-13 NMR using heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin as a chiral solvating agent (CSA) is discussed.

  Abfallfreie Gas/Festkörper-Diazotierung mit Stickstoffdioxid und quantitative Triazensynthese ohne Flüssigphase

  摘要：

  Solid diazonium nitrates (2a-j) are quantitatively obtained by reaction of crystalline anilines (1a-j) with gaseous nitrogen dioxide. Solid diazonium salts react quantitatively with dimethylamine to give the triazenes (4a-j). Wastes that are typical for the previous syntheses of these compounds in solution are avoided. Atomic force microscopic (AFM) investigations indicate long-range molecular movements due to phase rebuilding. The features thus formed are related to the known crystal structures of the starting anilines. The diazotations run to completion, because, after accumulation of product molecules, phase transformation to give the product lattices leads to crystal disintegration and thus to formation of fresh surface over and over.

  A method of qualitatively or quantitatively determining a component of a complex formed between at least one specific binding agent and its corresponding bindable substance. Said method comprises labelling at least one component of said complex with a marker which is easier to determine than the complex itself, whereby the marker used consists of latex particles which can be detected visually either by colour or fluorescence. Preferably the marker consists of coloured or colourable latex particles and the determination is based on the colour characteristics of the latex particles as such or, in the instance that colourable latex particles are used, on the colour characteristics of the coloured particles derived therefrom. The colour, respectively fluorescence signal is, if necessary after development, easily detected and optionally quantified. The invention further comprises coloured or colourable latex particles coated with specific binding proteins and test kits containing the same.

  convenient syntheses of aryl azocyclopropeniums and a study of their photochemical properties. Incorporation of the smallest arene leads to pronounced redshift of the π–π* absorbance band, compared to azobenzenes. Photoisomerization under purple or green light irradiation affords Z- or E-isomers in ratios up to 94% Z or 90% E, and the switches proved stable over multiple irradiation cycles. Thermal half-lives
