Carbenes generation zeolites

In summary, attempts were made to control the outcome of carbene reactions by including the corresponding 3//-diazirine precursors within the cavities of CyDs and FAU zeolites. Carbenes generated within the nanoscopic coniines of CyDs and FAU zeolites behave differently than those arising within conventional media. [Pg.251]

Chang and Silvestri [lb], reporting the conversion of methanol to hydrocarbons over zeolite ZSM-5, also favored a carbene mechanism for initial C-C bond formation. However, the complicity of free carbenes was considered unlikely from an energetics viewpoint, and a concerted mechanism was proposed for carbene generation with concurrent sp3 insertion into MeOH or DME. Later, the possibility of a sequential mechanism was considered [14]. [Pg.128]
