Primary Applications of Calcium Triflate (Calcium(II) Trifluoromethanesulfonate)
Calcium Triflate combines moderate Lewis acidity with excellent stability, enabling efficient performance
across multiple chemical and materials-science applications:
Lewis Acid Catalyst in Organic Synthesis:
Calcium Triflate is widely used as a mild Lewis acid catalyst, offering good selectivity and
functional-group tolerance in reactions such as:
Carbon–carbon bond-forming reactions
Friedel–Crafts alkylation and acylation
Aldol and related condensation reactions
Protection and deprotection of carbonyl compounds
Polymerization and Materials Chemistry:
Used as a catalyst or co-catalyst in polymerization reactions, including ring-opening and
coordination polymerizations, contributing to controlled molecular weight and polymer structure.
Green Chemistry Applications:
Due to its relatively low toxicity and moisture tolerance, Calcium Triflate is suitable for
greener reaction systems, including processes conducted in aqueous or mixed-solvent media.
Pharmaceutical and Fine Chemical Synthesis:
Applied in the synthesis of pharmaceutical intermediates and specialty chemicals where mild
reaction conditions and high selectivity are essential.
Academic Research and Catalyst Screening:
Frequently employed in research laboratories as a benchmark metal triflate for studying Lewis
acid-catalyzed mechanisms and reaction optimization.
Its role as a mild Lewis acid catalyst is discussed in
metal triflates as Lewis acid catalysts in organic synthesis.
