Any help would be appreciated...
Is it at all possible to isolate / extract platinum from compounds such as cisplatin or Oxaliplatin?
Here is the structure:
http://en.wikipedia.org/wiki/OxaliplatinOnce extracted would this result in Platinum or platinum black?
Would this catalyst be able to be utilized in further organic synthesis?
I have found several hints point to how to carry out this isolation but it always seems more geared towards refining metals for geological purposes.
So what I am hoping to find is a very detailed protocol involving the isolation or extraction of platinum and all that I can figure so far is that I will need aqua regia and heat!
Again, any help or advice on this will be greatly appreciated. I did find this previous posting and was wondering if this would be what I am looking for. It sounds a bit scary though as I will be working with well above a 1g scale.
..Take your used Pt catalyst, and dissolve it up by heating it in aqua regia (it takes a while to dissolve). Evaporate the solution, and convert the resulting chloroplatic acid H2PtCl6 to ammonium chloroplatinate, (NH4)2PtCl6.
This next bit is in the Org. Synth. prep for the Adams catalyst. Mix 1 part ammonium chloroplatinate with 10 parts AR sodium nitrate by weight in a porcelain crucible, and heat slowly in a full bunsen flame (fumehood), the sodium nitrate will fuse (~350 deg C), and release copious NOx fumes. Once the fusion has occurred, heat the mass at full flame for 20 minutes - ideally reaching 500-550 deg C (i have no idea how you would measure this kind of temperature, i just heated as hot as it will go). Cool to room temperature, smash the mass up, and add to water, stirring well. Filter off the fine brown solid (PtO2.xH2O), wash well with water, dry in a dessicator and then its ready to go..
