Borylation–Reduction–Borylation for the Formation of 1,4-Azaborines [PDF]
Organic Letters, 2023 Given the current interest in materials containing 1,4-azaborine units, the development of new routes to these structures is important. Carbonyl directed electrophilic borylation using BBr3 is a facile method for the ortho-borylation of N,N-diaryl-amide ...

C–H borylation catalysis of heteroaromatics by a rhenium boryl polyhydride [PDF]
ACS Catalysis, 2021 Transition metal complexes bearing metal–boron bonds are of particular relevance to catalytic C–H borylation reactions, with iridium polyboryl and polyhydrido-boryl complexes the current benchmark catalysts for these transformations.

Catalytic borylation of methane [PDF]
Science, 2018 Despite steady progress in catalytic methods for the borylation of hydrocarbons, methane has not yet been subject to this transformation. Here we report the iridium-catalyzed borylation of methane using bis(pinacolborane) in cyclohexane solvent ...

Decarboxylative borylation [PDF]
Science, 2017 Swapping boron acids for carbon acids Carbon-bound boronic acids and their esters are widely used as coupling partners to make carbon-carbon bonds. More recently, these chemicals have garnered pharmaceutical interest in their own right. Li et al.

Electrochemical Borylation of Carboxylic Acids [PDF]
Proceedings of the National Academy of Sciences, 2021 A simple electrochemically mediated method for the conversion of alkyl carboxylic acids to their borylated congeners is presented. This protocol features an undivided cell setup with inexpensive carbon-based electrodes and exhibits a broad substrate scope and scalability in both flow and batch reactors. The use of this method in challenging contexts is

Enhancing the Borylation Experience: Strategies for Heteroaromatic Borylation [PDF]
, 2015 Iridium-catalyzed C-H borylation is an attractive method for synthesis of heteroaromatic boronate esters. Disappointingly however, the Lewis-basicity of azinyl heterocycles limits their application in this methodology due to coordination to the iridium ...

Photoinduced Deaminative Borylation of Unactivated Aromatic Amines Enhanced by CO2 [PDF]
, 2021 Herein, direct unactivated C-N borylation of aromatic amines by a photocatalyst was achieved under mild and metal-free conditions. The C-N borylation of aromatic amines with bis(pinacolato)diboron (B2pin2) proceeded in the presence of a pyrene catalyst ...
