B2H6 can be prepared by NaBH4 and dimethyl sulfate?
I remember a method to prepare the B2H6 in situ for reducing the amide to amine. The method use the NaBH4 react with dimethyl sulfate (CH3O)2SO2 to
generate the B2H6 in situ. In the literature, it compare the reduction yelid of using B2H6 and NaBH4 + (CH3O)2SO2. But  I forgot the original literature and could't find it again !!!!!! I saw this method in
one of my book before, but I forgot it now.
Anybody can help me and give me some literature!!!!!
help!!!!!

The method that I recall is dissolving NaBH<sub>4</sub> in a glyme and adding dissolved iodine to liberate the diborane and borane. I
don't recall a method involving dimethyl sulfate though.

The stuff is spontanously inflammable in air, and may even react with nitrogen, so you will have to use an inert atmosphere.

any lewis acid can be used to liberate borane/diborane from NaBH4. try some FeCl3 for a start
