VERFAHREN ZUR HERSTELLUNG VON TERRYLEN-3,4:11,12-TETRACARBONSÄUREDIIMIDEN DURCH DIREKTSYNTHESE
摘要:
The invention relates to a method for the production of terylene-3,4:11,12-tetracarboxydiimides (I) in which the variables have the following meanings: R, R' independently = H, optionally substituted alkyl or cycloalkyl, aryl or heteroaryl, R1 = H or alkyl; R2 = H, alkyl, optionally substituted aryl or heteroaryl, whereby a perylene-3,4-dicarboxyimide (II) is reacted with a naphthalene-1,8-dicarboxyimide (III), where X = H, bromine or chlorine, in the presence of a base-stable, high boiling organic solvent and an alkali or alkaline earth metal base.
