Diisopinocampheylborane was originally prepared by hydroboration of excess α-pinene with borane, but it is now more commonly generated from borane-methyl sulfide (BMS). The compound can be isolated as a solid. However, because it is quite sensitive to water and air, this reagent is often generated in situ and used as a solution. Diisopinocampheylborane is monomeric, in contrast to diborane and many of its less bulky anal… Web18 apr. 2016 · The invention provides methods for storing boranes (e.g. B-allyldiisopinocampheylborane).
