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 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 Sn-O-Sn-O chain (Sn-O 2.17(9) and 2.29(9) Angstroem) in the monoclinic space group C2 (a=12.696(4), b=4.181(2), c=10.626(3) Angstroem and β=106.8(3) deg).

(β-Trimethylstannyl)alkyldiphenylphosphines can be readily prepared by addition of diphenylphosphine to the corresponding vinyltrimethyltin Me3SnCR=CH2 under free radical conditions.In contrast, free radical hydrostannation of the corresponding phosphines Ph2PCR=CH2 is a more complex process, and is apparently of little synthetic value.The title compound can be easily oxidised by potassium permanganate to give the corresponding phosphine oxides in good yields.Hydrostannation of model alkynyldiphenylphosphines (RCCPPh2, R=H, Me3Sn) occurs regiospecifically.
