Title:
PRODUCTION OF AROMATIC FLUORIDE
Document Type and Number:
Japanese Patent JPS6471824
Kind Code:
A
Abstract:
PURPOSE: To obtain an aromatic fluoride safely and in high yield, by reacting an aromatic diazonium halogenoborate with hydrogen fluoride or hydrogen fluoride and a base under light irradiation.
CONSTITUTION: An aromatic diazonium halogenoborate is reacted with hydrogen fluoride or hydrogen fluoride and a base under light irradiation at -50W100°C to give an aromatic fluoride. A high-temperature mercury vapor lamp may be cited as a light source used for light irradiation. Irradiation time is 5minW24 hr. An amine compound except a primary amine and an ether compound may be preferable as the base and the amount of the base used is 5W90wt.% based on sum of hydrogen fluoride and the base. The reaction can also be carried out in a solvent such as chlorobenzene, CCl4 or pentane to dissolve the aromatic fluoride but not hydrogen fluoride.
