Sila-Riechstoffe und Riechstoffe-Isostere. 11. Mitt. Vergleich von Carbinolen und Silanolen mit Thiocarbinolen und Silanthiolen

摘要: The thiocarbinolsRC(CH3)2SH withR=C6H5CH2 and C6H5CH2CH2 were prepared via reactions 2–5 compared in their odors (very unpleasant) with the fragrances of analogous carbinolsRC(CH3)2OH silanolsRSi(CH3)2OH. Silanethiols, by 6–8, smell less unpleasant than thiocarbinols but decompose easily presence catalytic amounts ammonium salts (eq. 9). Very pure hexenyl-methyl-vinylsilanethiol (“silathiolinalool”) decomposes contrarily under cyclization to a 1-sila-2-thia-cyclopentane derivative (E 1). differences odors, spite very similar structures, are discussed light theory ofAmoore (“Size structure molecules rule odor qualities”).
