             Synthesis of P2P from 3-phenyl-1-chloropropane by KrZ
-------------------------------------------------------------------------------

Dehydrohalogenation

Begin by purchasing 1kg of 3-Phenyl-1-chloropropane AKA 3-phenylpropyl chloride.
This should easily be had for $180 or less. It is unwatched and while many of
your suppliers might not have it in stock, they can all source it for you*.

* Clearly this customer knows his shit and is doing legitimate home research
  (Hey, he's not buying any fucking RP and hypophosphorous).

Next get yourself 800g of Potassium tertbutoxide ($140 per kg or less). Now all
we need is some tBuOH, go ahead and get 4L (Not more than $75).

Place the 1Kg of 3-phenylpropyl chloride, 800g Potassium tertbutoxide, and 2L of
tBuOH in a 5L RBF and stir well for 24-48hours. Slight heating (not refluxing)
might help, or then again it might hurt. This is all that has been tested so far.

When the 24 hous is up filter off the KCl which will fall out of solution during
the reaction. Take your remainder and distill off your tBuOH, vacuum distill and
collect a large allylbenzene fraction (BP will depend on your vacuum of course).
As soon as the allylbenzene stops coming over, shut it down. Youll be left with
a small brown-yellow mess in the flask and 645g of Allylbenzene or about an 85%
yield.

Oxidation

Place the 645g of Allylbenzene in a 4L Rossi wine jug, along with 3L of
anhydrous EtOH, 6.5g PdCl2, 20g CuCl2*2H2O, and 50ml of distilled water. By
balancing a stir bar on the dimple in the middle you can get it spinning nicely.
Now firmly attach an O2 input hose to the top of the jug (see other posts for
details). Pressurize the device to 45psi (numerous times this has been attempted
and none of them have resulted in the jug exploding) and stir vigorously for 8
hours. The cleanup for this reaction has already been covered far to extensively
elsewhere (spiceboys writeup on rhodium for example), so I wont get into it.
Once you have completed your extraction and distillation you will be left with
660g of very fun to play with P2P. You can either take this and perform NaBH4
reduction or Al/Hg or H2 or whatever your little heart desires.

Some additional notes;

* DMSO can also be applied as a cheap and easily accessable solvent for the
  dehydrohalogenation.

* Stirring should be vigorous, and the only as-yet tested reaction time is 48
  hours (not 24 as the last paragraph of the dehydrohalogenation would suggest.
