Abstract
Tricycloalkyltin chlorides e.g. tricyclohexyltin chlorides, which may be converted to the fungicide tricyclohexyl hydroxide, are made by reacting an organic tricycloalkyltin, in which the organic is not cycloalkyl and cycloalkyl is optionally substituted cyclohexyl, with organic tin trihalide.
