Acid-promoted denitrogenative Pd-catalyzed addition of arylhydrazines with nitriles at room temperature†
Abstract
The Pd(TFA)2-catalyzed denitrogenative addition proceeded with selective C–N bond cleavage of arylhydrazines with nitriles in the presence of DABCO and HFBA under air at room temperature. Aryl ketones could be easily synthesized via the hydrolysis of the ketimine moiety generated in situ without the need for additional water.
