Untersuchungen zur Basizität von Alkyl- und Silylakylaminen

Investigations on the Basicity of Alkyl and Silyl Alkylamines The basicity of N has been investigated in primary and secondary alkyl und silyl alkylamines by means of the v_C–D band shift of CDCl₃ associated to the amine group by potentiometrically determined pK_s-values, and by mass spectroscopically measured ionisation potentials. The results show a dependence on electronic and steric effects, but they do not give arguments for a conjugative interaction between N and Si,
