2-Fluoro-3-dimethylchlorosilylpyridine (A) and 3-fluoro-4-dimethylchlorosilylpyridine (B) were synthesized from the corresponding fluoro-lithio-pyridines and dimethyldichlorosilane at -76°C. The liquid products were unstable on standing. A and B were hydrolyzed in aqueous ammonia at room temperature to give disiloxanes which are stable crystalline solids. The new compounds were characterized by IR, ¹H NMR and MS.
