Abstract

A method for attaching haloarylsilanes to polymer support was developed. The polymer bound arylhalides were reacted with a variety of ArB (OH) 2 under the Suzuki cross-coupling reaction conditions and the coupled resins were cleaved by different electrophiles to give ipso-substitution products in good yields.
