One-pot tandem piperidinium acetate-mediated cyclocondensation of 1,3-bis-sulfonylpropan-2-ones with arylaldehydes generates tris-sulfonyl 3-arylphenols in moderate to good yields in refluxing toluene under easy-operational reaction conditions. A plausible mechanism is proposed and discussed. In the overall reaction process, water and sulfinic acid were generated as the byproducts. Various ammonium
