Abstract
Quinquiphenyl and other polyphenyls are formed by reduction of benzenediazonium sulphate in concentrated sulphuric acid and acetic acid with formic acid and copper powder.1 A mixture of 4-iododiphenyl, 4-iodoterphenyl and silver powder gives quinquiphenyl.1 4-Diphenyl lithium and cyclohexanedione yield the diol (I). This is easily dehydrated to the dihydro compound (II) which is dehydrogenated to quinquiphenyl by heating with selenium. Even contact with air achieves dehydrogenation.2
