Resumen:
Metal carbenes are a fundamental type of organometallic intermediates which display very unique reactivity patterns. Due to the limitations presented by most of the stablished metal-carbene precursors, we propose the use of alternative carbene sources based on the concept of aromative decarbenation, or retro-Buchner reaction. In the presence of cationic gold(I) complexes, 7-subtituted cycloheptatrienes can undergo a decarbenation or retro-Buchner reaction, generating gold(I) carbenes upon release of a molecule of benzene. We have extended this concept for the development of new and more reactive carbene precursors, based on the release of different aromatic or polyaromatic molecules, through catalysis of metals other than gold.
