detailed study of the thermolysis of (Z)-4,5-diethynyl-4-octene (4) is presented. This reaction gives high yields of products formed by rearrangement and intramolecular and intermolecular trapping of the intermediate 1,4-dehydrobenzene 5. The kinetics of the solution pyrolysis of 4 in the presence and absence of trapping agent establish that the 1,4-dehydrobenzene is a discrete intermediate on the pathway
