A copper(II) metal-organic hydrogel as a heterogeneous reusable catalyst for the synthesis of 1,3-oxathiolane-2-thiones from the reaction of CS and epoxides.

A copper(II) metalorganic hydrogel has been synthesised using the ligand ((2-hydroxynaphthalen-1-yl)methyl)-L-threonine and characterised. The hydrogel is an efficient, reusable catalyst for the selective synthesis of 1,3-oxathiolane-2-thiones from the reaction of CS and epoxides under solvent-free conditions.
