Lithium amidotrihydroborate (LiH2NBH3, LAB) is a new and highly nucleophilic reducing agent that is easily prepared by deprotonation of the commerical reagent borane-ammonia complex (H3NBH3) with n-BuLi in tetrahydrofuran (THF) at 0 °C. LAB is found to be a superior reagent for the transformation of tertiary amides into the corresponding primary alcohols.
氨基三氢硼酸锂(LiH 2 NBH 3,LAB)是一种新型的高度亲核还原剂,可通过在0°C在四氢呋喃(THF)中用正丁基锂将商业试剂硼烷-氨络合物(H 3 NBH 3)去质子化而轻松制备C。发现LAB是将叔酰胺转化成相应的伯醇的优良试剂。
