And the article contained the following:
In this paper a versatile and efficient method for synthesis of vicinal halohydrins via regioselective ring opening of epoxides by using polymer-supported HCl and HBr under solvent-free conditions is described. The regioselective ring opening of various epoxides is achieved under mild and solvent-free conditions by using crosslinked poly(4-vinylpyridine)-supported hydrochloric acid, [P4-VP]HCl and crosslinked poly(4-vinylpyridine)-supported hydrobromic acid, [P4-VP]HBr, under heterogeneous conditions. [P4-VP]HCl and [P4-VP]HBr act as both solid proton source and as nucleophile and consequently, the corresponding β-halohydrin product is prepared [P4-VP]HCl and [P4-VP]HBr can be easily regenerated and reused several cycles without their activity changing appreciably. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Safety of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione
