In the solvent free oxidation of BDO to GBL a 50% potassium permanganate and 50% 20/80 mixture of copper sulphate pentahydrate and alumina are added to BDO at a ratio of 2 mmmol BDO to ~4g oxidant. I'm not sure what the mechanism of this reaction looks like, so I was wondering if anyone could help me figure out a more precise ratio of BDO:oxidant, as I'm not all that confident with "~4g".
Many Thanks,
