Sodium trimethylsiloxide is an organosilicon compound with the formula NaOSi(CH3)3. It is the sodium salt of the conjugate base derived from trimethylsilanol.[1] A white solid, its molecular structure consists of a cluster with Na-O-Na linkages on the basis of closely related compounds.[2]
The salt is used to prepare trimethylsiloxide complexes by salt metathesis. Trimethylsiloxide is a lipophilic pseudohalide.[3][4]
It is a source of oxide dianion.[5][6]
