Hydrogen-metal exchange reactions using butyllithium have been studied on cross-linked poly(4-methylstyrene) to prepare polymer-bound benzyllithium reagent, which is a valuable starting material for functionalized resins. A simple one-step lithiation of pendant tolyl group of poly(4-methylstyrene) was achieved with a degree of lithiation as high as 50% using t-butyllithium in tetrahydrofuran.

Key words
