Abstract
A 1,1-diphenylethane and an aromatic compound such as benzene are reacted in the presence of a Friedel-Craft's catalyst to provide a compound having two 1,1-diaromatic substituted ethane groups, dehydrogenation provides a bis(1-phenylethenyl)aromatic compound.
Claims9
A method for the preparation of bis(1-phenylethenyl)aromatic compounds, the steps of the method comprising providing a 1,1-diphenylethane, disproportionating the 1,1-diphenylethane in the presence of a Friedel-Craft's catalyst to form a bis(1phenylethyl)aromatic compound and subsequently dehydrogenating the bis(1-phenylethyl)aromatic compound to a bis(1-phenylethenyl)aromatic compound.
