Application of 586-76-5This research focused onvinyl heterocyclic compound preparation stereoselective green chem; terminal olefin sulfonyl amide tandem dehydrogenative annulation palladium catalyst. The article conveys some information:
A palladium-catalyzed tandem dehydrogenative [4 + 2] annulation of terminal olefins with N-sulfonyl amides via C(sp2)-H activation, allylic C(sp3)-H activation, and homoallylic C(sp3)-H elimination processes has been developed. Promoted by the DMSO ligand, various benzamides, heterocyclic arylamides, alkenyl carboxamides, and com. olefins are found to be efficient substrates to construct important heterocyclic compounds bearing a vinyl substituent with high E stereoselectivity. Using air as the terminal oxidant also provides a great advantage regarding environmental friendliness.4-Bromobenzoic acid(cas: 586-76-5Application of 586-76-5) was used in this study.
4-Bromobenzoic acid(cas: 586-76-5) has been used to study the metabolic fate of 2-,3-and 4-bromo benzoic acids in rat hepatocytes incubation using high temperature liquid chromatography. It was used in bromine-specific detection of the metabolites of 2-,3-and 4-bromobenzoic acid in the urine and bile of rats by inductively coupled plasma mass spectrometry.Application of 586-76-5
