Title: Method for producing biaryl compound
Inventor: KUSUMOTO TETSUO
IPC: C07C25/22
Filed: 2001-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing a biaryl compound at a low cost. SOLUTION: This method for producing a biaryl compound is characterized by reacting the arylboronic acid with an aryl halide or an aryl triflate in the presence of an organic metal complex as a catalyst and in the coexistence of a base at a higher temperature than the boiling point of a used solvent at the ordinary pressure, under a pressurized condition. Thereby, on the production of the biaryl compound whose acquisition is difficult due to its complicated production method, the reduction in the amount of the used organic metal complex catalyst, the package supply of the catalyst, and the shortage of a reaction time are possible.  The biaryl compound can industrially easily be produced at a low cost by the production method, and the obtained biaryl compound is highly useful as a medicine, an agrochemical, a functional material such as a liquid crystal display material, or a synthetic intermediate for the substances.
