A Traceless Directing Group for C H Borylation. Angewandte Chemie International Edition 2013 , 52 (49) , 12915-12919. DOI: 10.1002/anie.201306511.
A Traceless Directing Group for C-H Borylation | Request PDF The protocol developed by Smith and Maleczka can be used as an example here, with the Bpin group serving as a traceless directing group for the selective C−H borylation of indoles into the 3 Ni-catalyzed traceless, directed C3-selective C-H A highly efficient and general protocol for traceless, directed C3-selective C-H borylation of indoles with [Ni(IMes)2] as the catalyst is reported. Activation and borylation of N-H bonds by [Ni(IMes)2] is essential to install a Bpin moiety at the N-position as a traceless directing group, which enables the C3-selective borylation of C-H bonds. The N-Bpin group which is formed is easily
Intramolecular (directed) electrophilic C–H borylation
Jul 06, 2018 Iridium-catalyzed diborylation of benzylic C–H bonds We describe a regioselective diborylation of primary benzylic C–H bonds catalyzed by [Ir(COD)OMe]2 and 4,4′-di-tert-butyl-2,2′-bipyridine (dtbpy). The hydrosilyl group acts as a traceless directing group, providing access to a range of 1,1-benzyldiboronate esters in good yields. Transformations of the 1,1-be Celebrating our 2018 prize and award winners C-H Activation for the Construction of C-B bonds
Weinreb amides are a privileged, multi-functional group with well-established utility in classical synthesis. Recently, several studies have demonstrated the use of Weinreb amides as interesting substrates in transition metal-catalyzed C-H functionalization reactions. Herein, we review this part of the literature, including the metal catalysts, transformations explored so far and specific
