lene; some transformations of these compounds are described. Friedel–Crafts acetylation of 2-methylbiphenylene gave mainly the 3-acetyl and 3,7-diacetyl derivatives. Friedel–Crafts acylation of biphenylene with ethoxalyl chloride could be made to give either the 2-glyoxylic ester or a mixture of the mono ester and the 2,6-diglyoxylic ester. Appropriate reduction of biphenylene-2-glyoxylic acid gave
