Oligomeric benzylsulfonium salts: facile benzylation via high-load ROMP reagents.

Mianji Zhang1, Daniel L Flynn, Paul R Hanson.   

Abstract

The development of high-load, oligomeric benzylsulfonium salts, generated via ring-opening metathesis polymerization, and their utility in facile benzylations of various nucleophiles is reported. These oligomeric sulfonium salts exist as free-flowing powders and are stable at room temperature. After the benzylation event, purification is attained via simple dry load/filtration, followed by solvent removal to deliver products in excellent yield and purity.
