CAS 161337-67-3: hafnium trifluoromethanesulfonate

Hafnium(IV) trifluoromethanesulphonate

Hafnium trifluoromethanesulfonate is a recyclable catalyst for the mononitration of o-nitrotoluene. It serves as a catalyst for homogeneous methoxycarbonylation and hydrocarboxylation reactions of phenylacetylene. It is also used as a reactant for direct Friedel-Crafts reactions of chromene hemiacetals, aminomethylation reactions under Lewis acidic conditions and prins-type cyclization reactions. It is also involved in the direct polycondensation of lactic acid. Further, it is used in cationic benzylation reactions, chemoselective thioacetalization and transthioacetalization of carbonyl compounds. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Hafnium(IV) trifluoromethanesulfonate is a compound that has been used as an inhibitor in carbohydrate chemistry. Hafnium(IV) trifluoromethanesulfonate inhibits the reaction between malonic acid and acetic anhydride in an asymmetric synthesis, which results in a mixture of diastereomers. It also suppresses apoptosis by inhibiting the activation of caspase-3, which is one of the primary pathways for apoptosis. The mechanism behind this inhibition is not entirely clear but may be due to the hydroxyl group present on the aromatic hydrocarbon or its acidic nature. Hafnium(IV) trifluoromethanesulfonate has anticancer activity and has been shown to inhibit tumor growth in vivo with low toxicity.
