A new air-stable Si,S-chelating ligand for Ir-catalyzed directed: Ortho C-H borylation

A new air-stable Si,S-chelating ligand has been developed and used in an iridium-catalyzed ortho C-H borylation reaction with a broad substrate scope. This study provides the first example of using a sulfur-containing ligand in the catalytic C-H borylation process. It provides a rapid, efficient, and economical method for the preparation of organoboron compounds. This journal is

Carbazole derivatives and organoelectro luminescent device using the same

PURPOSE: A carbazole derivative is provided to drive an organic electroluminescent device at low voltage and to improve brightness when the derivative is used in an organic layer of the organic electroluminescent device, thereby improving economic efficiency. CONSTITUTION: A carbazole derivative is denoted by chemical formula 1. An organic electroluminescent device comprises a first electrode, a second electrode, and one or more organic layers between the first and second electrodes. The organic layers contain the carbazole derivative of chemical formula 1. The organic layers are selected among a hole injection layer, a hole transport layer, a functional layer with hole injecting and transporting functions, a light emitting layer, an electrode transport layer, and an electron injection layer. The light emitting layer contains one or more host compounds and one or more dopant compounds. The host compound is a carbazole derivative of chemical formula 1.

Cleavage of C(aryl)?CH3 Bonds in the Absence of Directing Groups under Transition Metal Free Conditions

Organic chemists now can construct carbon–carbon σ-bonds selectively and sequentially, whereas methods for the selective cleavage of carbon–carbon σ-bonds, especially for unreactive hydrocarbons, remain limited. Activation by ring strain, directing groups, or in the presence of a carbonyl or a cyano group is usually required. In this work, by using a sequential strategy site-selective cleavage and borylation of C(aryl)?CH3 bonds has been developed under directing group free and transition metal free conditions. Methyl groups of various arenes are selectively cleaved and replaced by boryl groups. Mechanistic analysis suggests that it proceeds by a sequential intermolecular oxidation and coupling of a transient aryl radical, generated by radical decarboxylation, involving a pyridine-stabilized persistent boryl radical.
