A highly efficient and general nucleophilic substitutionreaction between dialkyl H-phosphonates or diarylphosphine oxides and triarylmethanols catalyzed by HOTf (trifluoromethanesulfonic acid) has been developed. It provides an atom-economical protocol for the synthesis of various symmetrical and unsymmetrical phosphorus-substituted triarylmethanes that constitute an emerging family of potent anticancer
