Synthesis of Novel Inorganic Fluorine Compounds by Direct Fluorination.

摘要

It has been found possible to preserve metal-carbon and metalloid-carbon bonds during direct fluorination. The reaction of dimethylmercury with fluorine gives bis(trifluoromethyl)mercury in 6.5% yield. Fluorination of tetramethylsilane has led to the isolation of the new polyfluorotetramethylsilanes of the following type, Si(CH3)x(CH2F)y(CHF2)z, x+y+z = 4. Also characterized were compounds containing Si-CF3. It has been possible to synthesize tetrakis(trifluoromethyl)germanium in 63,5% yield from the reaction of fluorine with tetramethylgermanium. Also characterized were many polyfluorotetramethylgermanes of the following type, Ge(CF3)x(CF2H)y(CFH2)z, z + y + z = 4. (Author)
