Abstract
An environmentally benign procedure for the synthesis of vicinal nitrohydrins via the regioselective ring opening reaction of
epoxides with nitrite anion using silica-bound 3-{2-[poly(ethylene glycol)]ethyl}-substituted 1-methyl-1H-imidazol-3-ium
bromide as an effective heterogeneous phase transfer catalyst was described. Short reaction time, high yield of products, simple work-up procedure, and recyclability of the catalyst were some of the striking features of the present protocol. The recover ed catalyst could be reused five times without any loss in its catalytic activity and selectivity.
