| titleOfInvention | Producing process of (fluoroaryl) borane compound and producing process of tetrakis (fluoroaryl) borate derivative |
| abstract | A fluoroaryl magnesium derivative expressed bynGeneral Formula (1):n nwhere each of R 1 -R 5 represents a hydrogen atom, a fluorine atom, a hydrocarbon group, or an alkoxy group while at least one of R 1 -R 5 representing a fluorine atom, and Xa represents a chlorine atom, a bromine atom, or an iodine atom; and n boron halide expressed by General Formula (2) :n BXb 3 nwhere Xb represents a fluorine atom, a chlorine atom, a bromine atom, or an iodine atom, are reacted with each other in a solvent (a) containing diethyl ether and/or tetrahydrofuran, after which the resulting reaction solution is added to a solvent (b) having a higher boiling point than diethyl ether and/or tetrahydrofuran while diethyl ether and/or tetrahydrofuran are distilled nout. Consequently, it has become possible to obtain an(fluoroaryl)borane compound expressed by General Formulan(3):n nwhere each of R 1 -R 5 represents a hydrogen atom, a fluorinenatom, a hydrocarbon group, or an alkoxy group while atnleast one of R 1 -R 5 representing a fluorine atom, Xbnrepresents a fluorine atom, a chlorine atom, a brominenatom, or an iodine atom, and n represents 2 or 3, fromnwhich magnesium halide produced as a by-product isnseparated and removed, selectively in a simple manner atna low cost. |
