A facile and highly regioselective Pd-catalyzed oxidative coupling of N-tosylhydrazones providing efficient access to 2,3-disubstituted-1,3-butadienes has been developed. This process features readily available starting materials and mild reaction conditions. Further transformations of the obtained dibranched 1,3-dienes, through Diels-Alder reactions and indene synthesis, are also demonstrated, which reveal their great potential for synthetic utility.

It is shown that acid-catalyzed docomposition of the 1,2-dioxetane derivative, 3,3-dimethyl-7,7-diphenyl-1,2-dioxaspironona-5,8-diene, obtained from 1-isopropylidene-4,4-diphenyl-2,5-cyclohexadiene, gives 1-methyl-1-(o-terphenyl-4'-yl)ethyl hydroperoxide, bisperoxide, 1-(1-hydroperoxy-1-methylethyl)-4,4-diphenylcyclohexa-2,5-dien-1-ol, and o-terphenyl-4'-ol, along with the usual dioxetane-scission product, 4,4-diphenyl-2,5-cyclohexadienone.The distribution and yield of these products depend on acidic agents and/or conditions employed.
