NaBH4 in the presence of sodium bisulfate (NaHSO4·H2O), a weakly acidic reagent, efficiently reduces a variety of carbonyl compounds such as aldehydes, ketones, α,β -unsaturated aldehydes and ketones, α-diketones and acyloins to their corresponding alcohols in acetonitrile under heterogeneous condition. Reduction reactions were accomplished at room temperature or under reflux condition
NaBH
4在存在
硫酸氢钠(NaHSO
4·H
2O)的情况下,作为一种弱酸试剂,能够高效地将各种羰基化合物如醛、酮、α,β-不饱和醛和酮、α-二酮和酰基酮在
乙腈中在非均相条件下还原为它们相应的醇。还原反应可在室温或回流条件下完成。
