Treatment of ortho-​(trimethysilyl)​aryl phenylsulfonates with a sol. fluoride source initiates a Truce-​Smiles rearrangement leading to the formation of functionalized bi-​aryls [e.g., I → II (74​%)​]​. This new carbon-​carbon bond-​forming reaction proceeds without recourse to transition metal catalysis, under mild reaction conditions and with good functional group compatibility. Safety: precautions should be taken in handling poly-​nitro aroms. to avoid detonation.
