Reduction of esters, amides, and ketones by N,N-diethylaniline borane is accelerated by catalysts derived from spiroborate complexes. Esters are reduced at ambient temperature in less than 4 h with this amine borane and 5 mol % spiroborate 6. Functional group selectivity shows ketone and tertiary amide reduction is faster than ester or nitrile reduction.
N,N-二乙基苯胺硼烷对酯,酰胺和酮的还原作用是由螺硼酸酯络合物衍生的催化剂来加速的。用该胺硼烷和5 mol%的螺硼酸酯6在室温下不到4小时即可将酯还原。官能团的选择性表明,酮和叔酰胺的还原速度快于酯或腈的还原速度。
