Sila-Riechstoffe und Riechstoffisostere. - XII : Geruchsvergleiche homologer Organoelementverbindungen der vierten Hauptgruppe (C, Si, Ge, Sn)

Abstract

Homologous compounds of the linalool type R(CH3)2El-OH (with R = C6H5CH2 and C6H5CH2CH2) as well as their derivatives R(CH3)2El-OCH3 and [R(CH3)2El]2O show, in dependence of El = C, Si, Ge and Sn partly similar, but sometimes very different characteristics of odor. Unexpected are high qualities of fragrance with El = Ge, whereas derivatives with El = Sn remain scentless, obviously owing to polymerization. Noteworthy are the strong differences of odor in the system C6H5CH2El(CH3)3 from C via Si and Ge up to Sn, standing fully contrary to the postulation of Amoore whereupon smell qualities are only controlled by size and shape of molecules. C6H5CH2Sn(CH3)2OH (A1Sn) crystallizes as poly-µ-hydroxo-benzyldimethyltin with an one dimensional SnOSnO chain (SnO 2.17(9) and 2.29(9) A°) in the monoclinic space group C2 (a = 12.696(4), b = 4.181(2), c = 10.626(3) A° and ß = 106.8(3)°).
