Abstract Tetrakis (4-acetoxyphenyl and 4-benzoyloxyphenyl) ethenes 1f and 1g 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 by nitration, Raney-Ni reduction and subsequent ...
