Hello! I need something about following things. It is very important to me:
1. Oxidation of carboxylic acids to chinones with presence of diiode pentaoxide (I2O5), potassium peroxodisulphate (K2S2O8), potassium permanganate (KMnO4) or potassium dichromate (K2Cr2O7);
2. Iodation. Inserting of iodium to the hydroxochinaldine acids ring by using diiode pentaoxide (I2O5);
3. Sulfuration of hydroxochinaldine acids by using tetraphosphorus decasulphide (P4S10);
4. Anything about Lawesson reagents.
I rely on your help because it is a very important case to me.
