QUINOLINIUM ION DERIVATIVES, PROCESS FOR THE PRODUCTION OF THE DERIVATIVES, PRODUCTS MADE BY USING THE SAME, AND REDUCTION AND OXIDATION METHODS WITH THE DERIVATIVES
Reported is a novel palladium(II)‐initiated Catellani‐type reaction that utilizes widely accessible aryl boronic acids as the substrates instead of aryl halides, thereby greatly expanding the existing scope of this powerful transformation. This borono‐Catellani reaction was promoted by cooperative catalysis between Pd(OAc)2 and the inexpensive 5‐norbornene‐2‐carbonitrile. Practicality is the striking

The present invention provides a process for producing an oxidation reaction product of an aromatic compound, having excellent environmental load reduction performance, cost reduction performance, etc. Provided is a process for producing an oxidation reaction product of a raw material aromatic compound by reacting the raw material aromatic compound with an oxidizing agent. The process further uses an electron donor-acceptor linked molecule. The process includes the step of: reacting the electron donor-acceptor linked molecule in an electron-transfer state, the oxidizing agent, and the raw material aromatic compound, thereby generating an oxidation reaction product resulting from oxidation of the raw material aromatic compound.
and convergent strategy for the assembly of atropisomeric o-terphenyls with 1,2-diaxes via palladium/chiral norbornene cooperative catalysis and axial-to-axial diastereoinduction. Readily available aryl iodides, 2,6-substituted aryl bromides, and potassium aryl trifluoroborates are used as the building blocks, laying the foundation for diversity-orientedsynthesis of these scaffolds (46 examples).

A new coupling partner: Vinylacetate couples with organoboroncompounds in the presence of a rhodium catalyst; carbon–carbon bond formation occurs on the vinylic carbon attached to the acetoxy group. Conventional nickel and palladium catalysts were found to be ineffective for the reaction.
