Organometallic and Metal-amide Precursors for Transition Metal and Lanthanide Cluster Complexes with Interesting Electronic an Magnetic Properties Woodruff, Daniel [Thesis]. Manchester, UK: The University of Manchester; 2012. Alkali metal silylamides are soluble in a range of organic solvents, where they exist as aggregates, and are commonly used in organic chemistry as strong sterically hindered bases. They are also extensively used as precursors for the synthesis other bis(trimethylsilyl)amide complexes (see below).
