The life and legacy of Thomas Midgley Jr.
Although little known to the general public, Thomas Midgley Jr., an American chemist and inventor, made two inventions which had fatal impacts on the Earth’s atmosphere, namely tetraethyl lead as an additive to fuels and Freon 12 as a refrigerant
Formation and structure of the oxygen-centered lead thiolate cluster Pb5O(SRF)(8)center dot 2C(7)H(8) [R-F=2,4,6-tris(trifluoromethyl)phenyl]
The unusual pentanuclear lead thiolate cluster PbsO(SRF)(8).C2H8 (3) (C7H8 = toluene) has been obtained by oxidation of Pb(SRF)(2) (2) with dry air and structurally characterized. The central oxygen atom is coordinated to three lead atoms in a trigonal planar fashion. The coordination sphere of the other two lead atoms is completed by coordination of toluene molecules
