Abstract
9-Borabicyclo (3.3.1) noname (9-BBN), a relatively stable solid dialkylborane, can be used to reduce a wide variety of reducible chemical compounds, including both organic and inorganic compounds. The stability of the reagent greatly reduces the operating difficulties encountered with other dialkylboranes having similar reduction properties, which are thermally and hydrolytically unstable.
Claims11
A process for the reduction of a chemical compound having a reducible functional group selected from carbonyl, nitro, azo, oxime, isocyanate, sulfone, sulfonic acid, sulfoxide, thioamide, thioketone, methylenephosphorane, iminophosphorane, iminosulfurane, phosphine oxide, thiophosphate and epoxide groups, which process comprises reacting said compound with an effective quantity of 9-BBN at a temperature below the decomposition temperature of the reactants or the resulting products.
