Synthesis and Stabilities of 3-Borylated Indoles [PDF]
We report herein that 3-pinacol boronic esters undergo facile protodeborylation in the presence of palladium catalysts and base, and this contributes significantly to the generation of nonborylated indole byproducts in the B2Pin2-mediated palladium ...

Iridium-Catalyzed Silylation of C-H Bonds in Unactivated Arenes: A Sterically Encumbered Phenanthroline Ligand Accelerates Catalysis. [PDF]
We report a new system for the silylation of aryl C-H bonds. The combination of [Ir(cod)(OMe)]2 and 2,9-Me2-phenanthroline (2,9-Me2-phen) catalyzes the silylation of arenes at lower temperatures and with faster rates than those reported previously, when ...

Direct borylation of terrylene and quaterrylene
The preparation of large rylenes often needs the use of solubilizing groups along the rylene backbone, and all the substituents of the terrylenes and quaterrylenes were introduced before creating the rylene skeleton.

A General Procedure for the Regioselective Synthesis of Aryl Thioethers and Aryl Selenides Through C–H Activation of Arenes [PDF]
A general procedure for the synthesis of aryl thioethers and aryl selenides in one-pot through sequential iridium-catalyzed C–H borylation and copper-promoted C–S and C–Se bond formation is described.

Palladium-catalyzed borylation of aryl (pseudo)halides and its applications in biaryl synthesis
A facile and efficient palladium-catalyzed borylation of aryl (pseudo)halides at room temperature has been developed. Arylboronic esters were expeditiously assembled in good yields and with a broad substrate scope and good functional group compatibility.
