Mild deuteration method of terminal alkynes in heavy water using reusable basic resin†
Abstract
The mild and efficient deuteration of terminal alkynes (mono-substituted alkynes) proceeded in the presence of a basic anion exchange resin, WA30, which is a polystyrene polymer bearing a tertiary amine residue on the aromatic nuclei, in heavy water (D2O) at room temperature. WA30 could be easily removed by a simple filtration and repeatedly reused.
