nabh4

After nabh4 addition is complete and mixed for a few hours after can you let the mix sit for a few hours and the freebase oil layer will rise to the top and can be seperated? this eliminates the need for dcm or toluene extraction but does effect yield.

https://bbgate.com/threads/one-pot-amphetamine-synthesis-from-p2np-with-nabh4-cucl2-1kg-scale.70/ Can I use STAB instead of NabH4 in this route, people in the forum say that STAB can be used in case of glacial acetic acid

Nabh4 is not available for personal purchase in my country, so I wonder if anyone has used STAB instead of Nabh4, as far as I know STAB is a mild reducing agent, but I don't know if it can reduce P2NP, and cyanoboron Sodium hydride is highly toxic and I'm not going to try this, if anyone has...

Well Howdy there folks! There’s a lot of info and conversations and loosely, reliable syntheses on many forums discussing using 2 particular reagents, but I need something objective. I’m looking for this “gold standard” synth everyone is having success with using Sodium Borohydride and...

NaBH4 is added to RBF and suspended in DCE or THF 3 molar equivalent Glacial acetic acid are added drop wise and the mixture was stirred until no more Hydrogen gas evolved. and after this can I vacuum distillate solvent with little heat and take it to dryness?
