diameters of up to 600 microm have been derivatized completely, via bromine-magnesium exchange and interception with electrophiles, to yield high quality solid-supportedreagents, scavengers and solid supports for use in diversity-oriented synthesis.

Co-polymerised 4-bromopolystyrene has been converted to a range of polymer-supportedreagents and scavengers by bromine–magnesium exchange using Oshima's trialkylmagnesate complex followed by quenching with a variety of electrophiles. Mitsunobu, halogenation and Wittig reactions, were explored to assess the utility of the resins for target oriented and diversity oriented synthesis.
