Abstract
On thermolysis, o-carboranyl substituted 4-aryl-4-hydroxycyclobutenone s 5a-d undergo electrocyclic ring opening followed by ring closure to yield substituted butenolides 6a-d. This is in contrast to the thermol ysis of cyclobutenones which generally produces substituted quinones. Published by Elsevier Science Ltd.
