Parallel Modes of C−H Bond Activation Initiated by CpMo(NO)(CH2CMe3)(C6H5) at Ambient Temperatures

The molybdenum nitrosyl complex Cp*Mo(NO)(CH2CMe3)(C6H5) reacts at room temperature via elimination of neopentane or benzene to form the transient species Cp*Mo(NO)(CHCMe3) and Cp*Mo(NO)(η-C6H4). These reactive intermediates effect the intermolecular activation of hydrocarbon C−H bonds via the reve...

Description
Summary:The molybdenum nitrosyl complex Cp*Mo(NO)(CH2CMe3)(C6H5) reacts at room temperature via elimination of neopentane or benzene to form the transient species Cp*Mo(NO)(CHCMe3) and Cp*Mo(NO)(η-C6H4). These reactive intermediates effect the intermolecular activation of hydrocarbon C−H bonds via the reverse of the transformations by which they are generated. Thermolysis of Cp*Mo(NO)(CH2CMe3)(C6H5) in pyridine yields the adducts Cp*Mo(NO)(CHCMe3)(NC5H5) and Cp*Mo(NO)(η2-C6H4)(NC5H5), and the benzyne complex has been characterized by X-ray diffraction.
