Fentin acetate is a chemical compound from the group of organotin compounds and a carboxylic acid ester of fentin.

Production and representation

Fentin acetate may be obtained by reaction of chlorobenzene with magnesium, tin tetrachloride in a Grignard reaction followed by reaction with acetic acid.

Properties

Fentin acetate is a flammable colorless solid with an aromatic, slightly sour smell, which is practically insoluble in water. It decomposes when heated. Fentin acetate is stable in the dry state, but rapidly hydrolyzed in the presence of water.

Use

Fentin acetate is used as a fungicide. It can also be used as a herbicide against algae in rice fields, as well as a molluscicide. It was developed in the 1950s by Van der Kerk and Luijten. It was approved in Germany 1971-1997, in East Germany until 1994.

The European Commission decided in 2002 not to include Fentin acetate in the list of permitted pesticide active substances in Annex 1 of Directive 91/414/EEC.

In Germany, Austria and Switzerland, no plant protection products containing this active ingredient are allowed.
