Iridium-Catalyzed Borylation of Secondary Benzylic C-H Bonds Directed by a Hydrosilane was written by Cho, Seung Hwan;Hartwig, John F.. And the article was included in Journal of the American Chemical Society in 2013.Product Details of 61150-57-0 This article mentions the following:
Most functionalizations of C-H bonds by main-group reagents occur at aryl or Me groups. The authors describe a highly regioselective borylation of secondary benzylic C-H bonds catalyzed by an Ir precursor and 3,4,7,8-tetramethyl-1,10-phenanthroline as the ligand. The reaction is directed to the benzylic position by a hydrosilyl substituent. This hydrosilyl directing group is readily deprotected or transformed to other functional groups after the borylation reaction, providing access to a diverse set of secondary benzylboronate esters by C-H borylation chem. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0Product Details of 61150-57-0).
2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Product Details of 61150-57-0
