448-61-3, 2,4,6-Triphenylpyrylium tetrafluoroborate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: To a suspension of the corresponding amine (2.0 mmol) and 2,4,6-triphenylpyrylium tetrafluoroborate (2.0 mmol) in EtOH (20 mL) in a round bottle flask was added Et3N (2.0 mmol). The mixture turned deep-brown while the educts dissolved and was stirred for 30 min at rt followed by the addition of AcOH (4.0 mmol) and heating under reflux conditions for additional 2 h. The product precipitated during the reaction. The product was dissolved directly in the flask with little acetone at the reflux temperature after the reaction was finished (no further precipitate occurred). After cooling down to rt the product crystallized as a yellow solid, which was filtered off, washed with cold EtOH and pentane and dried in vacuo., 448-61-3
The synthetic route of 448-61-3 has been constantly updated, and we look forward to future research findings.
