i was talking about the colour AFTER stripping off the DCM, look at his writeup:
[LabTop, 08-31-01, 'The ONE and ONLY buffered Performic']
... "Turn off the stirrer after these 24 hours, allow the two layers to settle. Separate off the bottom layer (DCM), and extract the remaining top residue-layer 2 times with a small amount of DCM, and add these to the already separated main DCM body. Take this combined portion to a 22 liter Rotavap or conventional distillation machine, distill off the DCM in 15 liter portions, and collect all the resulting ORANGE SYRUP portions ... "
This confused me because my syrup was dark brownish almost black, it looked like safrole after izomerizing with koh. After doing all the washes like Rhodium told me, it was orange coloured, but LabTop is doing the washes after the glycolisation step.
The result was suprisingly good, i got 85g MDP2P from 125g Isosafrole after doing my first buff. performic. I'm sure the second try will give a higher result, but i can live with that. After trying Brightstar's and MM wacker recipes i got nearly the same result, except that they use much more safrole (160g/178g). So i think the buff. performic is the choice for my future experiments...
