All test of wacker with H2O2 and safrol have failed. If you want to test it, change conditions, dual phase with DCM or toluene, or acetic or alcoholic solution of safrol and PdCl2 or Pd(AcO)2 does not work, gives other product, presumably an aldehyde.
Ritter:
That Pd(OAc)2 / tBuOH-H202 Wacker does not produce MDP2P with safrole. It produces a damned near perfect yield of the aldehyde which is useless for our purposes. This was proved by TLC . The sample was tested against safrole, isosafrole, 3,4MD propiophenone and MDP2P on whatman MK6F silicagel plates using 97:3 toluene/ethyl acetate mobile phase. The rf of the product produced by that oxidation was different than all of the mentioned compounds and also aminated w/ MeAM perfectly leaving me to conclude it was the aldehyde.
Don't repeat the same thing, but you can research other conditions...
