Abstract:

The 1:1 adduct produced in the reaction between tert-butyl isocyanide and dialkyl acetylenedicarboxylates was trapped by alkyl 2-fluoro-anilino-2-oxo-acetates or ethyl 2-oxo-2-(trifluoromethylanilino)-acetate to produce functionalised ketenimines in good yields. Dynamic NMR effects were observed in the 1H NMR spectra of these compounds as a result of restricted rotation around the single bond linking the aryl group to the ketenimine system. The free energy of activation (ΔG≠) for this process is 64.9–66.5 kJ mol−1.

Pd/CPhos-catalysis provides direct arylation/cyclisation of methylene-linked bis-anilines to dibenzo[1,3]diazepines v, which are both non-(C2)-symmetrical and axially chiral.

These are substituted with a second aniline derivative, allowing modular preparation of (ortho-halo)aryl-aminal-linked arenes 4.

Abstract:

Biological co-metabolism is an economical and efficient technique for treating refractory organic matter, and in recent years, it has been widely used in the treatment of chlorophenol-containing wastewater. It has been found that many conditions affect the bio co-metabolism efficiency, such as the carbon source type, carbon source content, microorganism types, and environmental factors. The carbon source concentration experiment showed that when the dosage ratio of sodium acetate to black aniline powder was 1:2, the degradation rate of black aniline powder was 82%, and the removal rate was 92.

In 4-bromoaniline buffers or by action of methanolic hydrogen chloride, the compound III is opened to E and Z isomers of 2-amino-N-methyl-N-(2,4,6-trinitrophenyl)propanamide hydrochloride (IV).

Engineered myoglobins have recently gained attention for their ability to catalyze a variety of abiological carbene transfer reactions including the functionalization of amines via carbene insertion into N–H bonds. However, the scope of myoglobin and other hemoprotein-based biocatalysts in the context of this transformation has been largely limited to aniline derivatives as the amine substrates and ethyl diazoacetate as the carbene donor reagent. In this report, we describe the development of an engineered myoglobin-based catalyst that is useful for promoting carbene N–H insertion reactions ac

Abstract:

The [C2D5]+ species forms an adduct in the gas phase with ethyl acetate, ethylbenzene, and p-ethyltoluene, which subsequently unimolecularly eliminates C2H4 and C2D4 in approximately a 2:1 ratio. These results indicate that the adduct is not a weakly bound ion–molecule complex but a bonded species in which the C2D5 group has become equivalent to the C2H5 group present in the molecule; the preference for elimination of C2H4 is due to an isotope effect. From observations of the relative loss of C2H4 and C2D4 from [C2D5]+ adducts with other molecules containing a C2H5 group, it is concluded that
