Thermal and thionyl chloride induced cycloaromatizations of secondary and tertiary aryldiacetylene alcohols were studied. The secondary alcohol did not respond to thionyl chloride, but in all the other cases presumptive biradical intermediates evolved eit
Synthesis of Novel Enyne-Allenes, Their Thermal C2-C6 Cyclization, and the Importance of a Benzofulvene Biradical in the DNA Strand Cleavage

Novel enyne-allenes without acceptor substituents have been prepared from propargyl acetates by Pd-catalyzed addition of arylzinc chloride or by cuprate addition. Their thermal reaction afforded exclusively the C2-C6 and no Myers-Saito cyclization products. In one case, intermolecular hydrogen abstraction and DNA strand cleavage were observed.
