Tetrakis(4-acetoxy- and 4-benzoyloxyphenyl)ethenes 1f,g were obtained by acylation of tetrakis(4-hydroxyphenyl)ethene 1b. Ullmann etherification of 4,4’-dihydroxybenzophenone 2b and subsequent McMurry coupling yielded tetrakis(phenoxyphenyl)ethene 1i. The tetrakis( acetamidophenyl)ethene 1h was prepared in three steps from tetraphenylethene 1c via nitration, Raney-Ni reduction and acetylation. ...
