Photolysis of 3,5-diphenylisoxazole in argon matrices

Broadband irradiation of 3,5-diphenylisoxazole 1 in an argon matrix results in formation of azirine 3. Further irradiation of the matrix reduces the amount of azirine 3 with concurrent formation of ylide 4. Thus, it is theorized that the conversion of isoxazole 1 to azirine 3 goes through a triplet vinylnitrene 2 that does not intersystem cross to ketenimine 6. Hence, the reactivity of triplet vinylnitrene 2 is different from similar vinylnitrene intermediates with alpha-methyl substituents that intersystem cross to form corresponding ketenimines. Density functional theory calculations support the notion that the conjugation of the alpha-phenyl group to the vinylnitrene moiety in vinylnitrene 2 renders it more flexible than vinylnitrenes with alpha-methyl substituents, and therefore, vinylnitrene 2 intersystem crosses to azirine 3, rather than ketenimine 6.

A copper-based metal-organic framework as an efficient and reusable heterogeneous catalyst for ullmann and goldberg type C-N coupling reactions

A highly porous metal-organic framework (Cu-TDPAT), constructed from a paddle-wheel type dinuclear copper cluster and 2,4,6-tris(3,5-dicarboxylphenylamino)-1,3,5-triazine (H6TDPAT), has been tested in Ullmann and Goldberg type C-N coupling reactions of a wide range of primary and secondary amines with halobenzenes, affording the corresponding N-arylation compounds in moderate to excellent yields. The Cu-TDPAT catalyst could be easily separated from the reaction mixtures by simple filtration, and could be reused at least five times without any significant degradation in catalytic activity.

N-heterocyclic derivatives of 2,4-dihydroxybenzcarbothioamide as antimycotic agents

N-heterocyclic derivatives of 2,4-dihydroxybenzcarbothioamide were synthesized from sulfinylbis- (2,4-dihydroxybenzenethioyl) and commercially available heterocyclic amines. The composition and chemical structures were confirmed by IR, 1H NMR, EI-MS, and elemental analysis. For the estimation of potential activity in vitro the MIC values against 15 strains of dermatophytes, yeasts, and molds were determined. The strongest fungistatic potency was found for N-5?-(3?-oxobenzfurylidyne)-2,4-dihydroxybenzcarbothioamide in relation to all tested dermatophyte strains with MIC = 0.48-0.98 mug/mL. On the basis of the spectroscopic data the influence of N-heterocyclic substitution on antimycotic activity is discussed.

Update 1 of: Destruction and detection of chemical warfare agents

The review describes many mainstream efforts by various chemical and biochemical laboratories, there are also many smaller sets of studies and single papers that investigate new systems undertaken in the hope that informative or useful results can be obtained. review describes many mainstream efforts by various chemical and biochemical laboratories, there are also many smaller sets of studies and single papers that investigate new systems undertaken in the hope that informative or useful results can be obtained families of materials, nanoscience, and enzymology continue to evolve naturally out of the continuing efforts of the research laboratories worldwide. Contamination of agents during their lifetime (synthesis, storage, unwanted deployment, and finally, destruction or decontamination) impacts human health and the environment. Systems based on microorganisms are essential to be included in a discussion of decontamination. New softer and polymer-based materials such as those at surfaces are probably more promising for a greater range of applications than rigid particles. A very important topic for the study of the decomposition of nerve agents and closely related compounds is still solid-phase surfaces. The most important consideration in protection is separating, and keeping separate, the toxic agent from personnel. Optimal personal protection has yet to be realized.
