✦ Synopsis
Polystyrene-bound dioxirane containing a five-methylene spacer arm between the polymer matrix and reagent function has been prepared and investigated as a new class of recyclable oxidising reagent for various organic substrates. The new reagent was found to oxidise alkenes to epoxides, pyridines to N-oxides and amines to nitro compounds in near-quantitative yields. The spent reagent could be regenerated to the dioxirane resin by a simple reaction without considerable loss in reactivity.

## Abstract A polymer‐supported ethylenediamine (EDA)–borane reagent was prepared under mild reaction conditions. The reagent was found to be efficient and selective in the reduction of aldehydes to the corresponding alcohols in high yields at room temperature. The polymeric reagent was prepared on
