The invention relates to a photosensitizer, which comprises a compound with a thiadiazolo[3, 4-g]quinoxaline structural unit, and the photosensitizer has structural characteristics of an intramolecular electron donor and an electron acceptor, has a relati

Organic photosensitizer on basis of pyrazine [2,3-g] quinoxaline, method for preparing organic photosensitizer and photodynamic application thereof

The invention provides a photosensitizer. The photosensitizer comprises compounds on the basis of pyrazine [2,3-g] quinoxaline structural units. The photosensitizer has the advantages that the photosensitizer has the structural features of intramolecular

Monomer 5, 6-Diphenyl-1.2.4-Traizinic Derivatives and the Use Thereof

The invention relates to the use of 5,6-diphenyl-1,2,4-triazinic compounds of general formula (I), wherein cycle penetrating bonds display an ortho, meta or para indifferent substitution position, identical or different R1 and R2 represent a hydrogen, fluoride, chloride or bromine atom, C1 to C12 linear or branched alkyl, C1 A C18 linear or branched hydroxy, alkoxy poly(ethoxy)-alkoxy with a C1 to C4 alkyl fragment and an ethoxy number ranging from 1 to 4, amino or mono or di-alkylamino with a C1 to C4 alkyl fragment group, R3 represents a chlorine atom, a hydroxy, amino, a phenyl possibly 1 to 3 times substituted by a hydroxy radical situated at least in a para or phenyl position possibly 1 to 3 times substituted in an ortho, meta or para position by a C1 to C12 alkoxy or cyano or alkymino group with a C1 to C7 alkyl fragment in the form of active sun filters or light-protective agents and to cosmetic composition containing said compounds.

Samarium diiodide promoted formation of 1,2-diketones and 1-acylamido-2-substituted benzimidazoles from N-acylbenzotriazoles

N-Acylbenzotriazoles, when treated with samarium diiodide in THF, undergo self-coupling reaction to afford 1,2-diketones in good to excellent yields; while when treated with samarium diiodide in CH3CN, they undergo ring-opening reaction to afford 1-acylamido-2-alkyl (or aryl) benzimidazoles in reasonable to good yields. A plausible mechanism was suggested.

Formation of 1,2-diketones by samarium diiodide promoted reaction of N-acylbenzotriazoles

Transformation of N-acylbenzotriazoles 1 into 1,2-diketones 2 in good to excellent yields has been realized by the use of samarium diiodide at room temperature.
