摘要

Addition of 1 mol equiv of borinic esters to lithium monoethoxyaluminohydride in ethyl ether at 0 OC results in a facile and rapid precipitation of the dialkoxyalane as a solid, producing the corresponding lithium dialkylborohydride in quantitative yield. The reaction is quite general, applicable to borinic esters of widely varied structural requirements. These derivatives are very stable and can be stored under nitrogen at 25" C without hydride loss ...
