The use of a compound of formula (I) wherein X is (i), (ii) or (iii), formula (i), formula (ii), formula (iii) Y is O, S(O), NR, CRR, CRR&#x2014;CRR, O&#x2014;CRR, S(O)&#x2014;CRR, NR&#x2014;CRR, CRR&#x2014;O, CRR&#x2014;S(O), CRR&#x2014;NR, SO&#x2014;NR, NR&#x2014;SO, NR&#x2014;O or O&#x2014;NR; m is 0, 1, or 2; the ring (T) formula (T) is a 5- or 6-membered aromatic or heteroaromatic ring; Rto Rare specified organic groups and n and is 0, 1, 2, 3 or 4; or salts or N-oxides thereof or compositions containing them in controlling insects, acarines, nematodes or molluscs. Novel compounds are also provided. 

Method of combating and controlling insects

Compounds of formula (I), wherein the substituents are as defined in claim, and the agrochemically acceptable salts and all stereoisomers and tautomeric forms of the compounds of formula I are suitable for use as herbicides. 

Herbicides

The invention relates to compounds of formula (I) wherein Ais C(RR); Ais C(RR); p is 1 or 2; q is 1 or 2; each of R, R, R, R, R, R, Rand Rwhich may be the same or different, represents hydrogen, methyl or ethyl and Ris C-Calkyl; Ris hydrogen, halogen, C-Calkyl or C-C-haloalkyl, and agronomically acceptable salts/isomers/enantiomers/tautomers/N-oxides of those compounds. 

Pyridine ketones with herbicidal effect

Compounds of the formula I in which the substituents are as defined in claimare suitable for use as herbicides.

Substituted pyridine herbicides

The present invention relates to a process for the preparation of compounds of formula I wherein the substituents are as defined in claim 1, by conversion of a compound of formula II reaction of that compound with a compound of formula IVX&#x2014;C(O)&#x2014;Q,&#x2003;&#x2003;(IV)wherein X is a leaving group, to form a compound of formula V and treatment of that compound in the presence of a base with catalytic amounts of cyanide ions.

Process for the preparation of cyclic diketones

The present invention relates to a process for the preparation of bicyclic 1,3-diketone salts of formula Iwherein R, R, Rand Rare each independently of the others hydrogen or C-Calkyl; A and E are each independently of the other C-Calkylene, which may be substituted once or up to four times by a C-Calkyl group, and Mis an alkali metal ion, alkaline earth metal ion or ammonium ion, by oxidation of a compound of formula IIto a compound of formula IIIand subsequent conversion to a compound of formula I either in the presence of a base and a catalytic amount of a cyanide or in the presence of an alkali metal alcoholate or alkaline earth metal alcoholate, and to novel bicyclic enol lactone intermediates of formula III for use in that process.

Process for the preparation of bicyclic diketone salts

The present invention relates to a process for the preparation of compounds of formula I:wherein the substituents are as defined in claimby conversion of a compound of formula II:reaction of that compound with a compound of formula IV:X&#x2014;C(O)&#x2014;Q&#x2003;&#x2003;(IV),wherein X is a leaving group, to form a compound of formula V:and treatment of that compound in the presence of a base with catalytic amounts of cyanide ions.
