Zur Frage der mechanochemischen Reaktion von Quarz mit organischen Verbindungen

Abstract: Durch Schwingmahlung von Quarz mit einigen Halogenverbindungen, aliphatischen und aromatischen Alkoholen sowie mit monomerem und polymerem Methacrylsäure‐methylester wurden Reaktionsprodukte erhalten, die bis zu 2,9% Kohlenstoff enthalten und deutlich hydrophob sind. Aus UR‐spektroskopischen Untersuchungen geht hervor, daß teilweise Bildung von SiOC‐Bindungen erfolgt ist.

“…Tetrachlorotolan, however, has been obtained from trichlorotoluene using red phosphorus in the presence of hydroiodic acid (25), elemental sulfur ( 1 3 , di-tertiarybutyl peroxide (26), and finely powdered tin (27), all reducing systems for the generation of radicals. Considering these examples, in the light of our own experiments, it was possible that the coloured species formed with 1,2,5-triphenylphosphole in boiling a ,a ,a-trichlorotoluene was the radical species 6 thermally produced in equilibrium with the phosphonium salt 5, neither of which arise to any significant extent at ambient temperatures.…”
