Racemisation

[Acab1312]

Hello,
I stumbled across an interesting article where the topic of racemisation of l-methamphetamine back to the racemic product is mentioned. Does anyone have experience in this regard?

Hello everyone would this work? I have a report

From this text I got the original idea. But the report is different, I have a PDF file in English, I would like the PDF, could it be published here without any problems or do you have to pay attention to something? Unfortunately, my native language is not English, so I do not understand the entire PDF.

General Procedure for the Racemization Experiments. A
0.06 M solution of amine (100 mg) and thiol (1.2 or 0.2 equiv)
in benzene was refluxed for 2 h (stoichiometric condition) or 7
h (catalytic condition) in the presence of AIBN (an overall
quantity of 20 mol % of AIBN was divided into three equal
portions (when reaction time > 2 h) that were added succes￾sively each 2 h). After concentration, the residue was diluted
with HCl (1 M), and the solution was washed with Et2O. The
aqueous phase was basified with saturated sodium carbonate
and extracted with Et2O. The pure amine was isolated after
drying on MgSO4 and concentration.

btcboss2022Did you ever test this? Curious if you were able to achieve racemic again.

There is a patent that outlines this process. The verbiage is incredibly cryptic. They use ciphers to identify which amines they are using which radical reactants and which processes. It's insanely difficult to decode. It has methamphetamine and azizobis...whatever AIBN, specifically written out. Want me to bring it over?
