Ruthenium-catalyzed intramolecular selective halogenation of O-methylbenzohydroximoyl halides: a new route to halogenated aromatic nitriles.
نویسندگان
چکیده
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.

متن کاملTandem regio- and diastereo-selective synthesis of halogenated C-vinyl glycosides from unactivated arylacetylenes.
A highly regio- and diastereo-selective synthesis of halogenated C-vinyl glycosides has been achieved from glycals and unactivated aryl acetylenes in the presence of halogenated Lewis acids via a tandem glycosylation-halogenation reaction. The Lewis acid used served the dual purpose of activating the allylic acetoxy group of glycals and serving as halogen source for Markovnikov addition across ...
متن کاملRuthenium(III) chloride catalyzed efficient synthesis of unsymmetrical diorganyl selenides via cleavage of dibenzyl and diphenyl diselenides in the presence of zinc.
[equation: see text] An efficient one-pot route to unsymmetrical diorganyl selenides has been developed by ruthenium(III) chloride catalyzed reactions of dibenzyl or diphenyl diselenides with alkyl halides in the presence of zinc. Organic iodides, bromides, and activated chlorides underwent the reactions efficiently. Unreactive organic chlorides also underwent the same type of selenation with s...
