The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1-Bromo-2-pentyne( cas:16400-32-1 ) is researched.Formula: C5H7Br.Rochette, Etienne; Desrosiers, Vincent; Soltani, Yashar; Fontaine, Frederic-Georges published the article 《Isodesmic C-H Borylation: Perspectives and Proof of Concept of Transfer Borylation Catalysis》 about this compound( cas:16400-32-1 ) in Journal of the American Chemical Society. Keywords: heteroarene borylation pyrrole indole arylboronate mercaptopyridine catalyst; borylated alkynylindole preparation crystal structure; mol structure borylated alkynylindole; pyrrole borylated preparation. Let’s learn more about this compound (cas:16400-32-1).
The potential advantages of using arylboronic esters as B source in the C-H borylation are discussed. The concept is showcased by using com. available 2-mercaptopyridine as a metal-free catalyst for the transfer borylation of heteroarenes, using arylboronates as borylation agents. The catalysis shows a unique functional group tolerance among C-H borylation reactions, tolerating notably terminal alkene and alkyne functional groups. The computational study of the mechanism is also described.
