Vinylcarbene complexes, Dotz benzannulation

A new chromahexatriene (118) route has been proposed for the mechanism of the Dotz benzannulation reaction between vinylcarbene complexes (117) and ethynes (Scheme 46). ... [Pg.481]

The mechanism of the Dotz benzannulation reaction has not been fully elucidated. The first step is the ratedetermining dissociation of one carbonyl ligand from the Fischer carbene complex, which is cis to the carbene moiety. Subsequently, the alkyne component coordinates to the coordinatively unsaturated carbene complex, and then it inserts into the metal-carbon bond. After the alkyne insertion, a vinylcarbene is formed that can lead to the product by two different pathways (Path A or Path b). ... [Pg.148]
