METHOD FOR PRODUCING OPTICALLY ACTIVE 2, 3-BISPHOSPHINOPYRAZINE DERIVATIVE AND METHOD FOR PRODUCING OPTICALLY ACTIVE PHOSPHINE TRANSITION METAL COMPLEX

In the method for producing an optically active 2,3-bisphosphinopyrazine derivative of the present invention, an optically active 2,3-bisphosphinopyrazine derivative represented by the following formula (3) is produced by the step of: preparing solution A containing 2,3-dihalogenopyrazine represented by the following formula (1) and a carboxylic acid amide coordinating solvent, lithiating an optically active R- or S-isomer of a hydrogen-phosphine borane compound represented by the following formula (2) to give a lithiated phosphine borane compound; adding solution B containing the lithiated phosphine borane compound to the solution A to perform an aromatic nucleophilic substitution reaction; and then performing a deboranation reaction. (For symbols in the formulas, see the description.)

Direct intramolecular carbon(sp2)-nitrogen(sp2) reductive elimination from gold(iii)

The reactivity of bidentate AuIII-Cl species, [(C^N)AuCl2], with a bisphosphine or carbon donor ligands results in reductive elimination. Combined experimental and computational investigations lead to the first evidence of a direct intramolecular C(sp2)-N(sp2) bond formation from a monomeric [(C^N)AuCl2] gold(iii) complex. We show that bidentate ligated Au(iii) systems bypass transmetallation to form C(sp2)-N(sp2) species and NHC-Au-Cl. Mechanistic investigations of the reported transformation reveal a ligand-induced reductive elimination via a key AuIII intermediate. Kinetic studies of the reaction support a second-order rate process.
