Abstract: The invention is a novel phosphonium salt, useful as an initiator or catalyst in the reaction of oxirane groups in an epoxy resin with aromatic carbonate and/or ester linkages in monomeric, oligomeric, or polymeric carbonates, esters, or estercarbonates. Phosphonium salt coupling reagents have acquired broad applications in peptide synthesis by virtue of their inertness to amino functional group and the consequent suppression of the potential guanidination side reaction at the step of amino acid activation and coupling.
