1]nonane, and borane-methyl sulfide rearranged on heating in situ at 100–160°C to open chain structures. Products after oxidation were the unrearranged cyclobutylmethanol, and 4-penten-1-ol, 1,4-pentanediol and 1,5-pentanediol. The unsaturated alcohol was the major product in reactions with a stoichiometric ratio of alkene to BH bonds, and the diols were formed with excess borane. With borane-methyl sulfide
由亚甲基环丁烷与硼烷/ THF,9-硼环[3.3.1]壬烷和硼烷-甲基硫醚加氢硼化得到的硼烷在100-160°C下原位加热重排成开链结构。氧化后的产物是未重排的环丁基甲醇,4-戊烯-1-醇,1,4-戊二醇和1,5-戊二醇。不饱和醇是烯烃与BH键化学计量比的反应中的主要产物,并且二醇与过量的硼烷形成。用硼烷-甲基硫醚作为加氢硼化试剂时,三甘醇二甲醚在100°C下的重排速率与初始烯烃/硼烷之比31或1.151或过量的甲基硫醚的存在无关。然而,当量的吡啶阻止了重排。在存在和不存在过量硼烷的情况下,使用硼烷/ THF在THF中的重排也以相当的速率发生。观察到很少或没有硼官能团异构化成环丁烷环。根据协调的四中心机制对结果进行解释,这需要一个空的硼轨道。
