Fungicide tricyclohexyl-tin hydroxide and chloride prodn. - by reacting organo-tricyclohexyl-tin with organo-tin trichloride and opt. hydrolysing (NL 12.12.77)
An organo-tricyclohexyl-tin cpd. of formula RSn(R'')3 (I) (where R'' is cyclohexyl opt. carrying >=1 substituents; and R is alk(en)yl, aralkyl or aryl) is reacted with an organotin trichloride of the formula R'SnCl3 (IIe (where R' is an organic group) and the resulti...

Abstract | An organo-tricyclohexyl-tin cpd. of formula RSn(R'')3 (I) (where R'' is cyclohexyl opt. carrying >=1 substituents; and R is alk(en)yl, aralkyl or aryl) is reacted with an organotin trichloride of the formula R'SnCl3 (IIe (where R' is an organic group) and the resulting mixt. of tricyclohexyltin chloride and diorganotin dichloride is opt. sepd. and the tricyclohexyltin chloride converted into tricyclohexyltin hydroxide. Tricyclohexyl-tin hydroxide is a known fungicide. The diorganotin dichloride byproduct and the oxide and hydroxide obtainable from it are intermediates for stabilisers for halogenated polymers or other biocides. the tricyclohexyltin chloride or hydroxide can readily be sepd. from the diorganotin by product. In an example, a solution of equimolar amounts of butyl-tricyclohexyltin and butyltin trichloride in commercial xylene is refluxed 22.5 hrs. to give a mixture consisting predominantly of tricyclohexyltin chloride and dibutyltin dichloride.
Obtention de composés organiques de l'étain. Des chlorures de tricycloalkylétain, par exemple les chlorures de tricyclohexylétain qui peuvent être convertis en hydroxyde de tricyclohexylétain comme fongicide, sont obtenus en faisant réagir un organotricycloalkylétain dans lequel le groupe organo n'est pas un cycloalkyle, et le groupe cycloalkyle est eventuellement un radical cyclohexyle substitue avec un trihalogénure d'organoétain. Intermédiaires de synthèse. |
