Reaktionsschritte
With stirring, 100 g of methyl 2-hydroxy-3,3,3-trifluoro-2-trifluoromethylpropionate was added dropwise to a mixture of 25.0 g sodium boron hydride, 500 g water and 500 g diethyl ether. Stirring continued for 10 hours, after which hydrochloric acid was added to quench the reaction. The organic layer was separated, concentrated, and distilled, obtaining 83.9 g of 3,3,3-trifluoro-2-trifluoromethyl-1,2-propane diol (yield 96%).
