Abstract

Some diethylamino derivatives of tin and titanium and pyrrolidino derivatives of silicon, germanium, tin and titanium react with diethylketone forming the corresponding amine, the oxide of the element and the enamines, namely 3-(N)-diethylamino-penten-2 and 3-(N)-pyrroldino-penten-2. The corresponding enamines and oxides were obtained, as well, by directly mixing the metal chlorides with ketone (methylethylketone or diethylketone) and amine (pyrrolidine or diethylamine), with the exception of SiCl 4,which does not react with diethylamine and these ketones. Another exception is GeCl 4, which does not react in the case of diethylamine with methylethylketone. The formulae of these products were established by means of i.r. and proton NMR spectra as well as by elemental analysis. A reasonable mechanism of the overall reaction is given.
