The reaction of organolithium reagents with methyl-dialkylborinates in hydrocarbon solvents proceeds readily with precipitation of lithium methoxide and the formation of the corresponding mixed organoborane: Consequently, simple filtration of the reaction mixture gives the mixed organoborane in high yield and purity. Other dialkylborane derivatives, such as the chloride and the hydride, are less desirable
有机锂试剂与甲基二烷基硼酸酯在烃溶剂中的反应易于进行,伴随着甲醇锂的沉淀和相应的混合有机硼烷的形成:因此,反应混合物的简单过滤以高收率和纯度得到了混合的有机硼烷。其他二烷基硼烷衍生物,例如氯化物和氢化物,不太适合作为底物,经常导致新烷基的异构化。
