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.

E,E- and E,Z-α-phenyl-α′-acetoxyorthoquinodimethanes have been prepared from the corresponding cis- and trans-1-acetoxy-3-phenyl-1,3-dihydrobenzo[c]thiophene-2,2-dioxides. The regio- and diastereoselectivity of the addition reactions with dimethyl fumarate, dimethyl maleate, maleic anhydride, and methyl crotonate have been determined. Abinitio calculations have been carried out on orthoquinodimethane and its α-phenyl and α-oxy derivatives. A correlation has been made between the steric and electronic properties of the orthoquinodimethanes and the regio- and diastereoselectivity of their Diels–Alder reactions.

Secondary Reactions

In continuation of the authors' earlier work on substances having a carbonyl bridge, it has been found that tetraphenylcyclopentadienone can be used as one of the components in the diene synthesis. Products are described resulting from the addition of maleic anhydride, maleic, fumaric, and acetylene dicarboxylic esters, and benzoyl phenylacetylene. In some instances the primary addition products containing a carbonyl bridge could be isolated. Tetraphenylbenzene derivatives result from secondary reactions. Benzalacetophenone, dibenzoyl-ethylene and diphenylketene did not add to tetraphenylcyclopentadienone.In the previously described reaction between maleic anhydride and anhydroacetonebenzil, certain intermediates have been isolated, confirming the mechanism suggested to account for the formation of a dianhydride.
