    Question regarding mdp2p Nabh4 reduction

    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.

    Can STAB use glacial acetic acid instead of NaBH4 in the absence of water? 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

    Can STAB replace NaBh4? cas:56553-60-7

    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...
