N-Hexyllithium and N-Octyllithium - nonpyrophoric variants - Anyone ever worked with them?

I've been doing a lot of reading on organolithium compounds lately and I was pleasantly surprised to hear that these two long-chain variants are not pyrophoric. Apparently N-Hexyllithium can be used in a solution up to 85%(!!!) without risk of pyrophoricity. Which I suppose means it could be stored in a normal reagent bottle and poured directly into reaction mixtures when needing to be used. I assume air reaction would still occur, but probably at a very minor extent.

That's pretty amazing, and I want to make some with the Lithium I have. Has anyone ever worked with these before?

Guard against atmospheric moisture. They will rapidly hydrolyze.
