Synthesis and1H NMR study of some organotin derivatives of diethanolamines

A number of organotin derivatives of diethanolamines (stannocanes) R2Sn(OCH2CH2)2NR', O(SiMe2CH2)2Sn(OCH2CH2)2NR', and Sn[(OCH2CH2)2NR']2 (R = Ph,cyclo-Hex; R' = H, Me, Ph) were synthesized and studied by1H NMR spectroscopy. The effect of steric factors on the ability of molecules of stannocanes to form associates in solutions is discussed.
