Silver nitrate promoted synthesis of tetraphenyl derivatives and diaryl ketones

Here in we report a novel silver nitrate-promoted oxidative pathway for the efficient synthesis of tetra substituted aryl derivatives (homodimers) and diaryl ketones. The oxidation of sp 3 C-H bond has been extensively studied by tuning the amount of the silver nitrate to afford the tetraphenyl or diaryl ketone, respectively with good selectivity under mild and simple conditions. This developed protocol offers a facile and general route to access a variety of value of tetraphenyl and diaryl ketones derivatives with moderate to good yield.
