when doing the KRV/SRV thing, using methanol as solvent and 1g pdcl2 per 50 mL safrole, why can't stirring be used instead of shaking? KrZ's method with DMF/O2 uses stirring and gets great yields. Why is it that shaking is emphasized in the KRV/SRV reaction? Swim's stirrer is pretty damn fast on 10, why would oxygen not be absorbed by stirring, but by shaking only? if stirring worked, it would be a much easier reaction, right? no more shaking, you could just set the thing on the stirrer and come back every half hour to repressurize.
