Lewis acid catalyst
Acts as a transition-metal-based Lewis acid catalyst, activating carbonyl and related electrophiles in organic synthesis. The triflate ligands confer strong oxophilicity characteristic of zirconocene triflate species.
Mukaiyama cross-aldol reactions
Used as a catalyst for Mukaiyama cross-aldol reactions, promoting carbon–carbon bond formation between silyl enol ethers and aldehydes or ketones.
Diels-Alder reactions
Serves as a Lewis acid catalyst for Diels-Alder cycloadditions, assisting [4+2] additions to construct six-membered carbocyclic and heterocyclic frameworks.
Polyoxometalate transfer chemistry
Employed as a reactant for polyoxometalate transfer in the synthesis of zirconocene polyoxometalate compounds, supporting inorganic and organometallic research.
Glycoconjugate and bioconjugate synthesis
Reported as a reagent in the synthesis of β-hFSH bearing chitobiose units, illustrating its use in specialised carbohydrate and glycoprotein-directed research.
