Reinvestigation of the Two-Step Synthesis of Sevoflurane

Journal: Iranian Journal of Pharmaceutical Research 2015

Abolghasem Moghimi, Ahmad Mollaei, Ali R Banan, Mojtaba Mahmoodian, Mostafa Vojdani, Sayyed Mojtaba Moosavi,

Improvements in the two-step synthesis of 1,1,1,3,3,3-hexafluoro-2- (fluoromehoxy)propane (Sevoflurane) that result in the product cost reduction, safety level enhancement and positive environmental impacts are described. This process consists of chloromethylation reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) followed by a halogen-exchange fluorination. This is the first synthesis of Sev...

The solubility of tris(pentane-2,4-dionato)chromium(III) (Cr(acac)(3)) in supercritical carbon dioxide (SC-CO(2)) containing organic modifiers (1,1,1,3,3,3-hexafluoro-2-propanol (HFP) and 3,5-bis(trifluoromethyl)phenol (BTMP)) of hydrogen-bond donors was investigated by UV/VIS spectrophotometry. A great solubility enhancement of Cr(acac)(3) in SC-CO(2) was accomplished by adding HFP and BTMP. T...

Enhanced reactivity of [hydroxy(tosyloxy)iodo]benzene in fluoroalcohol media. Efficient direct synthesis of thienyl(aryl)iodonium salts.

Journal: :Molecules 2010

Motoki Ito Chieko Ogawa Nobutaka Yamaoka Hiromichi Fujioka Toshifumi Dohi Yasuyuki Kita

In this manuscript, we report clear evidence for the generation of aromatic cation radicals produced by using [hydroxy(tosyloxy)iodo]benzene (HTIB) in fluoroalcohol solvents such as 2,2,2-trifluoroethanol (TFE) and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). The single-electron-transfer (SET) oxidation ability of HTIB to give cation radicals was first established by ESR and UV measurements. The r...
