In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 288-16-4, name is Isothiazole, introducing its new discovery. name: Isothiazole
Cycloaddttion, ring-opening, and other novel reactions of thiophenes
Synthetically useful reactions of thiophenes arid benzolb]thiophenes are reviewed in which the aromatzcity of the thiophene ring is lost either permanently or temporarilyj i.e. so-called “non-benzenoid” reactions. These include cyclcaddition reactions with arynes, hetarynes, carbenes, nitrsnes, olefins, acetylenes, ketones, and other substrates and various ring-opening reactions, e.g. of organometallic derivatives and 2-Aminothiophenes. Also reviewed are C-2 protonation and reactions of thiophenes at the sulprtur atom, e.g. alkylation. Brief reference is made to thiophene I, l-dioxideu and attention is drawn to other littie-used reactions of thiophenes of potential synthetic usefulness, e.g. inverted reactivity of thienyl-lithium compounds.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 288-16-4, and how the biochemistry of the body works.name: Isothiazole
