Abstract
This review collates synthetic procedures for the synthesis of different silyl anions,
which are valuable reagents for chemists, particularly in the field of organic synthesis
and organometallic chemistry. This includes the preparation of silyl anions of lithium,
sodium, potassium, rubidium, and cesium from group I metals and silyl anions of beryllium,
magnesium, calcium, strontium, and barium from group II metals. Synthetic procedures
for silyl anions of zirconium, hafnium, cadmium, and zinc are also covered. The synthesis
of group XIII silyl anions of boron and aluminum is also highlighted.
