Abstract:
A method for easily and inexpensively producing and purifying a fluoroaryl metal compound such as bis(pentafluorophenyl)dialkyltin which is less colored and has no impurities is provided. Hydrocarbon magnesium halide is reacted with fluoroaryl halide in a solvent including an ether solvent so as to obtain fluoroaryl magnesium halide, which is then reacted with an organic metal compound so as to produce a fluoroaryl metal compound. Tin is more preferable as a metal atom included in the organic metal compound. As for the ether solvent, chain ether solvents are preferable, more specifically, diisopropyl ether, dibutyl ether, and t-butylmethyl ether are more preferable. Besides, it is preferable that magnesium halide, which is a by-product of the fluoroaryl metal compound, is precipitated and removed, or treated with an acid.

Abstract:
A plurality of operators provided on a communication terminal, such as a portable phone, are assigned in advance to functions for generating tones, and a tone generation starting signal is generated in response to depressing operation, by a user, of any one of the operators. The communication terminal transmits, to a tone generator module, performance content data having added thereto operation time information representative of a time when the user's depressing operation has taken place. Upon receipt of the performance content data from the communication terminal, the tone generator module carries out a process based on the tone generation starting signal on the basis of the operation time information added to the performance content data.
Abstract:
Fluoroaryl magnesium halide is reacted with a boron compound so that a molar ratio of the fluoroaryl magnesium halide to the boron compound is not less than 3.0 and not more than 3.7, so as to produce a tetrakis (fluoroaryl) borate.magnesium compound. With this method, there occurs no hydrogen fluoride which corrodes a producing apparatus and requires troublesome waste water treatment.

The purified compound is reacted with a compound which forms a monovalent cation seed to prepare a derivative. Thus, a purifying method capable of efficiently and easily separating and removing colored components contained in tetrakis(fluoroaryl)borate compounds can be provided. Moreover, it is possible to provide a method capable of preparing a highly-pure tetrakis(fluoroaryl)borate derivative efficiently and at low costs.
