Something interesting: a classical demonstration in fluorous chemistry: 3 non miscible layers (organic-aqueous -fluorous).
The upper layer is an organic solution: Sudan IV (a red colored azo dye) dissolved in toluene.
The middle layer is water and methanol.
The bottom layer is a fluorous solution: perfluoroalkylated cobalt phthalocyanine (a blue colored complex) dissolved in perfluoroperhydrophenanthrene.
Growing crystals of a trifluoromethylthio substitued aromatic hydrocarbon.
Compounds that contain a trifluoromethylthio group (–SCF3) are found in many pharmaceutical and agrochemical products. Owing to their highlipophilicity and hydrophobicity, aryl trifluoromethylthio-ethers (ArSCF3) have attracted increasing attention from synthetic chemists to develop a efficient, high-yielded, and economical preparation of these molecules.
These crystals were prepared from an aryl thiolate with trifluoromethyl iodomethane (ICF3) what is a highly poisonous, carcinogen gas.
