1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane tetrahydroborate (BAAOTB) and tetrabutylammonium tetrahydroborate (TBATB) are used for the selective reductions of aldehydes, ketones, α,β-unsaturated carbonyl compounds, acid chlorides, azides, epoxides, and disulfides in t-BuOH and hexane/chloroform. ABBOAB with its rigid and bulky structure reacts more selectively than its analogue TBATB.
1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]辛烷四氢硼酸盐 (BAAOTB) 和四丁基四氢硼酸铵 (TBATB) 用于选择性还原醛、酮、α,β-不饱和羰基化合物、酰氯、叠氮化物、环氧化物和二硫化物在 t-BuOH 和己烷/氯仿中。ABBOAB 与它的类似物 TBATB 相比,具有刚性和庞大结构的反应更具选择性。
