Abstract
Triaroylbenzenes connected via m-xylyl, p-xylyl, 4,4'-biphenyl, and 1,3,5-b enzenetriyl linking units have been prepared in good yield by condensation of bis(enaminones) with aryl ethynyl ketones, The required bis(enaminones) were conveniently prepared starting from the corresponding bis- or tris(hal omethyl) linking units and 3-hydroxybenzaldehyde.
