Unusual thermal behaviour of tricyclo[4.1.0.02,7]hept-4-en-3-one (tropovalene)
Abstract
Thermolysis of tricyclo[4.1.0.02,7]hept-4-en-3-one constitutes an unusual bond reorganisation reaction in which the alkenic carbon atoms are responsible for the construction of the cyclobutene ring in the product, bicyclo[3.2.0]hepta-3,6-dien-2-one.
