                        Hazard Class4.3
                      • ⑴. 是一種有機硼烷,對濕氣和空氣比較敏感。
                      • ⑵. 用于有機合成中間體,被用作優秀的、溫和的和高度選擇性的還原試劑。具有較好的溶解度和較低價格的優勢,所以更廣泛地得到應用。它的分子中僅含有一個負氫離子,容易定量地控制試劑的用量;分子中有3個異丁基,自身具有較大的位阻,更容易在底物位阻小的區域發生選擇性反應。此外,三仲丁基硼氫化锂的還原能力明顯地受到反應溫度的影響。
                      • 在THF溶劑中,三仲丁基硼氫化锂與酮的還原反應可在低溫下進行。很多對反應條件敏感的官能團均不受到明顯的影響,例如:氰基、縮酮、縮醛、矽醚等。
