Chemical compound From Wikipedia, the free encyclopedia
Methylbismuth dichloride is the organobismuth compound with the formula CH3BiCl2. It is a pale yellow solid. The compound can be prepared in two steps from diphenylbismuth chloride, first by methylation with methylmagnesium chloride. Treatment of the resulting methyldiphenylbismuthine with hydrogen chloride cleaves the two phenyl-bismuth bonds.
