- ACTIVE COMPOUND COMBINATIONS HAVING INSECTICIDAL AND ACARICIDAL PROPERTIES
-
The novel active compound combinations comprising a compound of the formula (I-1) or (I-2) and the active compounds (1) to (26) listed in the description have very good insecticidal and acaricidal properties.

- Further study of tris(cyclohexyl)stannane compounds, Cy3SnX. Syntheses of the compounds with X = Br, I, N3 and NCS and redetermination of the crystal structures of Cy3SnX (X = Br and I)
-
Compound sythesis and far IR data are presented for various Cy 3SnX compounds. Redeterminations of the crystal structures of tris(cyclohexyl)tin bromide and iodide, Cy3SnBr and Cy 3SnI, confirm their molecular nature providing, in particular, a revised estimate of the Sn-I bond length, now 2.7463(6) ?. The nature of the solid state structure of Cy3SnCl is also discussed.

- Macrocyclic plant acaricides
-
Compounds of the formula I STR1 in which either R is methyl and there is a double bond in the 9,10-position, or in which R is hydrogen and there is a single bond in the 9,10-position, are highly active against Acarina which damage plants.

- Process for obtaining high-purity tricyclohexyl tin hydroxide on a high-yield basis
-
A process for producing tricyclohexyl tin derivatives, consists of a first phase in which Grignard reagent and tin tetrahalogenide are caused to react by feeding them into a reaction vessel in a molar ratio of 3:1, and a second phase in which after hydrolysis and anhydridization of the condensation mass, further Grignard reagent is added in an amount such as to maintain the total molar ratio, between the Grignard reagent and the tin tetrahalogenide, between 3.5:1 and 3.9:1.
