Anwendungen & Verwendung
Verwenden
Triphenylmethanol is used as a reagent in the research laboratory. It acts as an intermediate in the production of the commercially useful triarylmethane dyes. It is used in the preparation of triphenylmethane. It is also used as an antiproliferative agent. Further, it is used in the preparation of two-electron reduction product of pyrylogen. In addition to this, it reacts with triphenylphosphine oxide to form a 1:1 molecular complex. It serves as a specific clathrate host for methanol and dimethyl sulphoxide and forms clathrate inclusion complexes. Triphenylmethanol was used in the synthesis of of the two-electron reduction product of pyrylogen. It undergoes reduction to triphenylmethane by 9, 10-dihydro-10-methylacridine in the presence of perchloric acid.
Herstellung & Synthese
