Description

CAS: 161337-67-3 | C4H2F12HfO13S4 | 792.758 g/mol

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.
