mixture of ten aryloxides and heteroaryloxides. The feasibility of generating combinatorial libraries containing aryl and heteroaryl ethers was demonstrated by reacting the resin's with a single electrophile (n-butyl bromide) to afford mixtures of ether products. The advantages of using quaternary ammonium exchange resins over solution phase chemistry to prepare this library are discussed.

described. The observed rate constants for dediazoniation of the arenediazonium salts are almost completely independent of the salt. (CTA)X. and R'OH concentrations, consistent with rate-determining loss of N2 to give an aryl cation which reacts at diffusion-controlled rates with available nucleophiles. Salt-induced spectral shifts indicate formation of ion pairs in tbe ground state, and all our data
