The cross-linked microbeads with average diameter of 106-300 μm, [poly(EGDMA-MATrp)], were obtained by copolymerization reaction N-methacryloyl-L-(+)-tryptophan methyl ester (MATrp) ethylene glycol dimethacrylate (EGDMA) and successfully applied as a heterogeneous catalyst in conjugate addition nitromethane to substituted 2-iminochromenes aqueous media. A variety 2-amino-4-(nitromethyl)-4H-chro...

The design, synthesis, and development of a new class of modular, strongly basic, and tunable bifunctional Brønsted base/H-bond-donor organocatalysts are reported. These catalysts incorporate a triaryliminophosphorane as the Brønsted basic moiety and are readily synthesized via a last step Staudinger reaction of a chiral organoazide and a triarylphosphine. Their application to the first general...

In the title compound, [PtCl2(C13H21N5)]·0.5CH3NO2, the Pt(II) atom is coordinated in a slightly distorted square-planar geometry by two Cl atoms and two N atoms of the bidentate ligand. The (1,3,5-tri-aza-penta-diene)Pt(II) metalla ring is slightly bent and does not conjugate with the aromatic ring. In the crystal, N-H⋯Cl hydrogen bonds link the complex mol-ecules, forming chains along [001]. ...

In this work, we report a detailed investigation of the CH3NO2 chemistry effect on fuel-NO interactions for fuels methane and n-heptane using recently developed extensively validated H2/O2/CO/NOx/NH3/CH3NO2 baseline chemistry. general, model predictions show good agreement with temperature profiles major intermediate species in jet-stirred reactor experiments they capture subtle NO addition. Fo...

A well-known effect of amines, and also of water, on detonation characteristics of nitromethane (Nm) is discussed from the point of view of the published knowledge about the study of initiation reactivity of this nitro paraffin. It is documented that bimolecular and higher interactions during the initiation of Nm are impossible. The most widespread concepts of the primary steps of this initiati...
