Fuerstner, Alois published the artcileIron-Catalyzed Cross-Coupling Reactions, Quality Control of 24415-66-5, the main research area is iron complex cross coupling catalyst organometallic compound; aryl chloride triflate tosylate coupling iron catalyst; heteroaryl chloride triflate tosylate coupling iron catalyst; green chem iron complex cross coupling catalyst.
Simple iron salts such as FeCln, Fe(acac)n (n = 2,3) or the salen complex I turned out to be highly efficient, cheap, toxicol. benign, and environmentally friendly precatalysts for a host of cross-coupling reactions of alkyl or aryl Grignard reagents, zincates, or organomanganese species with aryl and heteroaryl chlorides, triflates, and even tosylates. An “”inorganic Grignard reagent”” of the formal composition [Fe(MgX)2], prepared in situ, likely constitutes the propagating species responsible for the catalytic turnover, which occurs in many cases at an unprecedented rate even at or below room temperature Because of the exceptionally mild reaction conditions, a series of functional groups such as esters, ethers, nitriles, sulfonates, sulfonamides, thioethers, acetals, alkynes, and -CF3 groups are compatible. The method also allows for consecutive cross-coupling processes in one pot, as exemplified by the efficient preparation of compound II, and has been applied to the first synthesis of the cytotoxic marine natural product montipyridine (III). In contrast to the clean reaction of (hetero)aryl chlorides, the corresponding bromides and iodides are prone to a reduction of their C-X bonds in the presence of the iron catalyst.
Journal of the American Chemical Society published new progress about Aryl chlorides Role: RCT (Reactant), RACT (Reactant or Reagent). 24415-66-5 belongs to class triazoles, name is 7-Chloro-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidine, and the molecular formula is C6H5ClN4, Quality Control of 24415-66-5.
