Pyrolysis of 1,6-diphenylhexa-1,5-diyne-cis-3-ene at 800-1000 °C leads to a mixture of 1- and 2-phenylbiphenylene, along with triphenylene. Formation of the two biphenylenes is taken as strong evidence of the rearrangement of a p-benzyne into a m-benzyne through a shift of one of the phenyl groups. Copyright

Aroyl chlorides react with acyclic and cyclic alkenes in the presence of a rhodium catalyst to give Mizoroki-Heck type and cyclization products, respectively. A rhodium-ethylene complex, [{RhCl(C2H 4)2}2], showed excellent performance for these reactions. Notably, the reactions can be conducted effectively under base- and phosphane-free conditions.
