Title:
PRODUCTION OF N-FLUOROPHENYLMALEAMIC ACID
Document Type and Number:
Japanese Patent JPH02184660
Kind Code:
A
Abstract:
NEW MATERIAL:A compound shown by formula (n is 1-5).
EXAMPLE: N-(4-Fluorophenyl)maleamic acid.
USE: An intermediate for maleimide derivatives. Useful as a material for wavelength conversion element using nonlinear optical response, optical switch, optical control device, etc.
PREPARATION: For example, maleic anhydride is reacted with a fluoroaniline derivative to give a compound shown by the formula. The reaction is carried out optionally in a proper solvent such as THF or xylene at 0-140°C for 30 minutes - 1 hour. 2-fluoroaniline, 2,3-difluoroaniline, etc., may be cited as the fluoroaniline derivative used.
