摘要

环己亚基-2-氨基甲酰基环己-1-烯胺与分子氧的反应不发生[4+2]环加成反应，而是主要通过烯胺到 3O2的单电子转移（SET）、质子转移（PT）和连续自由基 C-C 偶联生成二聚体，并形成过氧化氢副产物。

Reinvestigation of the mechanism of the enamine-mediated dioxygen activation

The reaction of cyclohexylidene-2-carbamylcyclohex-1-enylamines with molecular oxygen does not undergo a [4+2] cycloaddition reactions but leads mainly to a dimer via single electron transfer (SET) from the enamine to ³O₂, proton transfer (PT) and consecutive radical C–C coupling, an addition to the formation of hydroperoxide byproduct.

期刊介绍： The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water, aqueous solutions and other hydrogen-bonded liquids – Lubricants, polymer solutions and melts – Molten metals and salts – Phase transitions and critical phenomena in liquids and confined fluids – Self assembly in complex liquids.– Biomolecules in solution The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include: – Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.) – Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.) – Light scattering (Rayleigh, Brillouin, PCS, etc.) – Dielectric relaxation – X-ray and neutron scattering and diffraction. Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
