ABSTRACT:
Aromatic alkenes, especially diarylbutadienes are produced in a simple economic process by reaction of an anil with an organic compound having a non-aromatic unsaturated system conjugated with an aromatic system, and a terminal methyl group pendent from the non-aromatic unsaturated system; in particular the organic compound is a propenyl-substituted aromatic compound.
