| Abstract: | Spectroscopic studies (1H and 119Sn NMR, IR) showed that aldiminoalcohols reacted with bis(dimethylamino)dibutyltin via a transient secondary enamine. This compound was acidic enough to cleave the remaining SnN bond leading to oligomeric organotin enamines (5-coordinated tin atom) probably of E configuration. Several oligomeric species were in equilibrium and slight modification of the experimental conditions (+20 to +50°C) affected these equilibriums significantly. |
