General description

Triphenylmethanol forms 1:1 molecular complex with triphenylphosphine oxide. It is a specific clathrate host for methanol and dimethyl sulphoxide and forms clathrate inclusion complexes. It undergoes reduction to triphenylmethane by 9, l0-dihydro-10-methylacridine in the presence of perchloric acid.

Application

Triphenylmethanol was used in the synthesis of of the two-electron reduction product of pyrylogen.
