Abstract
Abstract This invention relates to organotin compounds containing fluorine which are particularly useful for forming fluorine-doped tin oxide coatings by the chemical vapor deposition method. In the preferred embodiment, the compound is monobutyldichlorotin trifluoroacetate, which is prepared by reaction of monobutyltin trichloride and trifluoroacetic acid.
