You find there also that Sodium borohydride, 0.5M in diglyme ( 2-methoxyethyl ether ) and Sodium borohydride, 2.0M in triglyme ( triethylene glycol dimethyl ether ) are the latests solutes used for storage and use of borohydrides. (Hint,hint,hint, Aa, when does
someone see the light?)

And that long post of mine about that fabulous website of that US professor about imines, you have to look that one up again.

Here come a few very interesting ones:

Nice piece of research, look at the references, don't forget to read
nr.2, and all the ones with those funky Indian names in them. He worked 4 years with prof.H.C. Brown at Purdue University.
And then they went on in India to research further, and came up with that link I gave once in Serious Chemistry as an answer to RevDrone's question about the inner workings of the NaBH4 onepot.
(Zinc borohydride has unique properties. Unfortunately, it is also not stable long enough to be offered commercially; hence,
it must be prepared in situ.)
