## Abstract The thermal isomerization of [1,4βD~2~]β (3a) and [1,2β^13^C~2~]benzene (1a) has been studied in excess hydrogen at 750β850Β°C with contact time less than 1.2 s and very low partial pressure in a quartz flow system. In both cases, the main isomerization products are the corresponding __m
In general, cyclic compounds containing the cyclopropyl-vinylcyclopropane ring system, upon thermolysis, undergo an internal [Za + 2a + Za] cycloaddition reaction,\* regardless of whether the second cyclopropane ring conjugates with the double bond or not. The pyrolysis of one of bis-homotropilidene
