Application
Tetrakis(pyridine)copper(II) triflate [Cu(OTf)2(py)4] is a general copper-based catalyst. It is commonly used to catalyze copper-mediated radiofluorination of arenes and heteroarene. It is also employed in C(sp3)-H functionalization/cyclisation of 2-amino-N,N-dialkylbenzamides to synthesize 2,3-disubstituted-4(3H)-quinazolinones.
Tetrakis(pyridine)copper(II) triflate can be used to catalyze:
- Intra and intermolecular aziridination of allylic carbamates and styrenes.
- 18F-fluorination of aryl boronic esters to generate fluroarenes applicable as radiotracers.
- Nucleophilic radiobromination of aryl borons with a radiobromide ion applicable in the preparation of radiobrominated pharmaceuticals.
