Litij Amoniak Brezova redukcija je bolj d kot l?

Iskreno vprašanje

 

[AuTiSTiC]

id raje uporabite natrij je cenejši in D ali L vse je odvisno od kemijske zmanjšano in mehanizem, je potrebno malo reševanja problemov naš učitelj uporabil dal uporabo teh vprašanj, ampak nekaj, kjer lahko odgovorite, aint enostavno in včasih ni mogoče povedati id ne s poskusi

It's true, the birch reduction isn't just for drugs, it is used an many synths, but you'd be remiss to use Na because the product of the birch reaction is 11% with sodium and 75% with lithium . Lithium is free from old batteries and sodium metal is expensive. The birch has 2 simultaneous reactions going on . If you use ephedrine/pseudoephedrine or any chiral precursor, you will get 95%+ the isomer with the chirality of the precursors. If your precursor is racemic, your product isnracemic
