Summary: | 1414242 Tri-(cyclohexylakyl)tin compounds M & T INTERNATIONAL BV 5 Oct 1973 [5 Oct 1972] 46659/73 Heading C2J The invention comprises compounds of the general formulae wherein R 1 -R 5 are each H or C 1-8 alkyl, X is Cl, Br, F, OH, R1COO-, phenoxy, -OR1 or -SR1 where R1 is C 1-12 alkyl or C 6-12 aryl, Y is -O-, -S- or a sulphate radical and n is 1-5. The compounds where X=Br are prepared by reacting bromine with a tetraorganotin compound of formula where Z is C 1-8 alkyl, C 2-8 alkenyl, phenyl or a further cyclohexylalkyl group, usually at -30 C. to 25 C. in a halogenated hydrocarbon or C 1-8 alcohol as solvent. Other compounds are prepared either by (a) reacting the bromine compound with HX or H 2 Y in the presence of an acid acceptor or with MX or M 2 Y where M is an alkali metal, or (b) reacting a hydroxy (X = OH) or oxide (Y = -O-) compound prepared as under (a) with HX, H 2 Y or (R1COO) 2 O. In the Examples, tris-(cyclohexylmethyl)- and tris-(cyclohexylpropyl)-tin bromides are prepared and the former is also converted into the oxide which in turn is converted into the acetate. The compounds have fungicidal and miticidal properties. |
