Abstract

A compound of formula (I): ##STR1## or a salt thereof; wherein Z represents a heterocyclic ring and R² and R³ are independently selected from hydrogen, nitrile, CONH₂, and SO₂ R⁴ wherein R⁴ is optionally substituted aryl, optionally substituted alkyl, aralkyl or cycloalkyl or R² and R³ together form an optionally substituted methylene group or a bond, intermediates, compositions, insecticidal and nematicidal use.

Claims

1. A compound of formula (IB):

##STR82## or a salt thereof;

wherein

R¹ is alkyl, aralkyl or acyl; and

R² and R³ are SO₂ R⁴ is optionally substituted aryl, optionally substituted alkyl, aralkyl or cycloalkyl.

2. A compound according to claim 1 wherein R¹ is methyl, ethyl or benzyl.

3. An insecticidal or nematocidal composition comprising a compound of formula (IB) as defined in claim 1 in combination with an agriculturally acceptable carrier.

4. A method of killing or controlling insect or nematode pests which method comprises administering to the insect or to a locus thereof an effective amount of a compound of formula (IB) as defined in claim 1.
