Title:
NEW PROCESS FOR PRODUCING FLUORINATED AROMATIC COMPOUND
Document Type and Number:
Japanese Patent JP3230099
Kind Code:
B2
Abstract:
PURPOSE: To provide a new process for easily and site-selectively fluorinating an aromatic ring by simple operation.
CONSTITUTION: A fluorinated aromatic compound is synthesized by reacting an N-aryl-N-hydroxyamide with diethylaminosulfur trifluoride (DAST). A fluorinated aromatic compound can be synthesized with simple operation in high yield using an easily handleable commercially available DAST. The process has generality. When a compound having N-hydroxyamide group substituted to an aromatic ring can be synthesized, a fluorine atom can easily be introduced into the aromatic ring to enable the synthesis of a fluorinated aromatic compound which is extremely difficult to synthesize by conventional process.
