Abstract: The present invention relates to derivatives of compounds which are known to be of use in the field of agriculture. These derivatives are differentiated from the parent active compound by virtue of being redox derivatives of the active compound. This means that one or more of the functional groups in the active compound has been converted to another group in one or more changes one or more of which may be considered to represent a change of oxidation state relative to the groups in the original compound. We refer to these compounds generally as redox derivatives. The compounds are of use as insecticides, herbicides and insect repellents.

Abstract: The present invention relates to compounds and their use as ligands, in particular, in metal catalyst complexes. The ligands of the invention are capable of binding to a solid support. The invention includes the ligands in their own right and when bound to a support and the compounds may be used to prepare metal catalyst complexes.
