Non-aromatic products from the base-catalysed isomerisation of octa-1,7-diyne
Abstract
The non-aromatic cyclic products from base treatment of octa-1,7-diyne have been characterised as 1-, 2-, and 3-methylcyclohepta-1,3,5-trienes and cyclo-octa-1,3,5-triene. A logical scheme to encompass the formation of these compounds, ethylbenzene, and all the isomeric xylenes is suggested.
