| Hazard Information | Back Directory | [Uses]
Catalyst for:
- Homogeneous methoxycarbonylation and hydrocarboxylation reactions of phenylacetylene
- Direct Friedel-Crafts reactions of chromene hemiacetals
- Aminomethylation reactions under Lewis acidic conditions
- Prins-type cyclization reactions
- Direct polycondensation of lactic acid
- Cationic benzylation reactions
- Chemoselective thioacetalization and transthioacetalization of carbonyl compounds
| [Uses]
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. | [reaction suitability]
