COA of Formula: C5H7Br. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about SmI2-catalysed cyclization cascades by radical relay. Author is Huang, Huan-Ming; McDouall, Joseph J. W.; Procter, David J..
Radical cyclization cascades that are catalyzed by SmI2 and exploit a radical relay/electron-catalysis strategy have been developed. The approach negates the need for a super-stoichiometric co-reductant and requires no additives. Complex cyclic products e.g., I, including products of dearomatization, containing up to four contiguous stereocenter are obtained in excellent yield. Mechanistic studies support a single-electron-transfer radical mechanism. This strategy provides a long-awaited solution to the problem of how to avoid the need for stoichiometric amounts of SmI2 and establishes a conceptual platform on which other catalytic radical processes using the ubiquitous reducing agent can be built.
Although many compounds look similar to this compound(16400-32-1)COA of Formula: C5H7Br, numerous studies have shown that this compound(SMILES:CCC#CCBr), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
