Air-stable Pd(0) catalyst bearing dual phosphine ligands: a detailed evaluation of air stability and catalytic property in cross-coupling reactions

We have synthesised an air-stable Pd(0) catalyst bearing donor and acceptor phosphine ligands (Complex1). This study revealed the long-term air stability and catalytic property of Complex1as a catalyst for cross-coupling reactions, where it was stable in air for eight months. DFT calculations revealed that the acceptor ligands in Complex1decreased the HOMO energy level, which provided the observed air stability. Complex1successfully served as a catalyst for direct C-H arylation reactions and Suzuki-Miyaura cross-coupling reactions, and catalysed the reaction of a relatively inactive substrate, 2-chrolopyridine, which could not be achieved by conventional, air-stable Pd(0) catalysts. Isolating the intermediates of the coupling reactions revealed that each intermediate possessed the donor ligand (PCy3), which was determined to be responsible for imparting the high catalytic activity exhibited by Complex1.

Synthesis of an Air-Stable Pd(0) Catalyst Bearing Donor and Acceptor Phosphine Ligands

We synthesized a new Pd(0) complex bearing π-acceptor ligands and a σ-donor ligand and confirmed that it exhibits high air stability and catalytic activity in direct arylation reactions. Moreover, stoichiometric reactions of the complex revealed that the σ-donor ligand does not dissociate from the Pd center.

Synthesis and n-type field-effect transistor characteristics of dioxopyrrolopyrrole derivatives

Dioxopyrrolopyrrole derivatives with electron-withdrawing groups have been synthesized and applied to organic field-effect transistors as n-channel semiconductors. A derivative with an intermolecular hydrogen-bonding network showed a good electron mobility up to 2.9 1012 cm2V 11 s11.
