Abstract

Various trialkylsilyl linked polymer supports have been prepared by reacting benzyl chloride resin and a di-Grignard reagent with CuBr·Me2S, followed by dialkylchlorosilanes. 4-Alkoxybenzyl type resin, Wang-Cl 2c and Argogel Wang-Cl 2d provided 4c and 4d at ambient temperature, whereas nonactivated resin, Merrifield 2a and Argogel-Cl 2b afforded 4a and 4b at 60°C. Primary and secondary alcohols 6-10 were attached to the alkyldiisopropyl-linked Wang type resin 4cA by a novel dehydrosilation with B(C6F5)3 as well as by conventional methods. © 2004 Elsevier Ltd.
