A highly efficient, metal-free, one-pot radical route to access diaryl ketones from aromatic aldehydes is reported. The protocol renders cross coupling of aromatic aldehydes with aryl diazonium tetrafluoroborates using inexpensive di-tert-butylperoxide (DTBP) as a radical initiator under mild conditions. The reaction offers a convenient alternative to the Friedel–Crafts acylation for the synthesis of diaryl ketones.
