One-step conversion of methoxysilanes to aminosilanes: a convenient synthetic strategy to N,O-functionalised organosilanes.

A straightforward substitution of silicon-bonded methoxy groups by a lithium amide leading to aminomethoxysilanes is presented. DFT calculations allow thermodynamic insight into the unusual equilibrium conditions. The applicability of N,O-functionalised organosilanes is exemplified by the convenient synthesis of an unsymmetrical methoxydisiloxane.
