Metal-Stabilized Quinone and Thioquinone Methides

摘要

In summary, an unprecedented sequence of reactions leading to the formation of the first thermally stable quinone methide is reported. The use of transition metals allows for the first time the full characterization (including X-ray analysis) of this type of compound, which is known to be a key intermediate in various biochemical processes. Even more reactive hioquino- nemethides can also be isolated and fully characterized.
