摘要

Thermolysis or photolysis of benzocyclobutenone (1) generates a reactive intermediate of considerable interest in organic synthesis, ¢t-oxo-o-quinodimethane (2), which undergoes facile [4+2] cycloaddition reaction with aldehydes, ketones and dienophiles such as maleic anhydride, dimethyl fumarate, benzoquinones and [60]fullerene.l,2, 3 Besides the diene moiety, another intriguing group in 2 is the ketene. Ketches are highly reactive towards a variety of compounds such ...
