Shaking vs. stirring

[TheBlindGenius]

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.

Shaking, and swilling(swirling)

Well, really you want to mix the contents right?
-Place 6-8 marbles into SRV
-watch yield go up,.

Try modifying the stirbar to get greater induction of the gasses.
A friend I know was working on an invention like this.
Basically involves drilling holes in a stirbar to cause induction of gasses into solution as it spins, try it sometime I don't give bad advise, unlike some people around here.
