- Visible-light photocatalytic activation of N-chlorosuccinimide by organic dyes for the chlorination of arenes and heteroarenes
-
A variety of arenes and heteroarenes are chlorinated in moderate to excellent yields using N-chlorosuccinimide (NCS) under visible-light activated conditions. A screening of known organic dye photocatalysts resulted in the identification of methylene green as the most efficient catalyst to use with NCS. According to mechanistic studies described within, the reaction is speculated to proceed via a single electron oxidation of NCS utilizing methylene green under visible-light photoredox pathway. The photo-oxidation of NCS amplifies the electrophilicity of the chlorine atom of the NCS, thus leading to enhanced reactivity as a chlorinating reagent with aromatic substrates.

- Ruthenium-catalyzed intramolecular selective halogenation of O-methylbenzohydroximoyl halides: A new route to halogenated aromatic nitriles
-
The intramolecular halogenation of O-methylbenzohydroximoyl halides in the presence of a Ru catalyst and the ligand diphenylacetylene afforded halo substituted aromatic nitriles in a highly regioselective manner. Further, substituted nitriles were converted into substituted tetrazole derivatives in the presence of NaN3 and I2.

- Process for preparing aromatic nitriles
-
The invention relates to obtaining aromatic nitriles of general formula: (R)n --C6 H4 --CN, where n=1, 2 or 3, and the rest R, identical or different represent an atom of hydrogen, chlorine or bromine or an alkyl, aryl, alkoxy, alkylamino, hydroxy or amino group, by a process comprising decarboxylating ammoxidation reaction, in an alkaline aqueous medium, at a pH higher than, or equal to, 13, in the presence of a catalyst based on one or several transition metals and an alkaline hydroxide, applied to an arylglyoxylic acid free or salified, of the formula: (R)n --C6 H4 --CO--COOH (where n and R have the above-mentioned meanings), or to one of its functional derivatives of the lactone, lactame or C1 -C3 -alkyl ester type.
