Abstract
2,3-Diphenylbutadiene has been prepared and its behaviour in addition reactions investigated. It forms a 1,4-dibromide, a 1,4-monobromide by addition of one molecule of hydrogen bromide, is reducible to the saturated hydrocarbon, combines with oxides of nitrogen to form two isomeric dinitrobutenes, and couples with diazonium compounds. In the diene synthesis, products have been secured from maleic anhydride, acetylene dicarboxylic ester, quinone, and α-naphthoquinone. In so far as comparable reactions have been examined, 2,3-diphenylbutadiene resembles 2,3-dimethylbutadiene in the types of products formed by addition. Certain discrepancies recorded in the literature among related dibromides have been cleared up.
