Poly(ethylene glycol)-Supported Copper(II) Triazacyclononane: an Efficient, Recoverable, and Recyclable Catalyst for the Cleavage of a Phosphodiester

1,3,5-Triazacyclononane macrocycle has been linked to the soluble polymer monomethoxy poly(ethyleneglycol) and its copper(II) complex efficiently catalyzes the hydrolysis of a model phosphodiester. The catalyst, easily recovered from the water solution, shows no appreciable loss of activity when recycled up to three times.
