A novel compound is having the structure, Formula (I): exhibits interesting odor characteristics, generally green in nature, particularly of a tomato leaf character, and so find use in perfumes and perfumed products.

Pyridine derivates useful as fragrance materials

4,8-cyclododecadienyl ketones having formula (I), in which R has up to 5 carbon atoms, are novel compounds exhibiting woody/amber odor characteristics which find use in perfumes and in perfumed products.

Fragrance compounds

Lewis acid-catalyzed reaction of an alkene, including cycloalkenes, with an epoxide to provide an aldehyde which may be reduced to the corresponding alcohol. The reaction products may be used to provide perfumes or perfume products.

Reaction of alkenes with epoxides, the products thereof and their use as fragrance compounds

The invention concerns 14-methyl-hexadecen-11-olide, 14-methyl-hexadecen-12-olide and 14-methyl-hexadecanolide and the use of these compounds as fragrance materials with musk odour. The invention also concerns 14-methyl-12-hydroxy-hexasecanolide, which is an intermediate in a novel process to prepare these compounds.

Pesticidal pyrimidine compounds

1. The use of a compound of the general formula ##STR1## in which n is 0 or 1

Composition containing a nitromethylene compound for use in combating

Nitromethylene compounds of general formula ##STR1## wherein R represents a hydrogen atom or an alkyl group, R.sup.1 represents a hydrogen atom or an alkyl group, n is 0 or 1, and Het represents an optionally substituted 3-pyridyl, 4-pyridyl or 5-isoxazolyl group, processes for their preparation, and their use as insecticides, are described.

Nitromethylene compounds

A herbicidal composition which comprises at least one carrier and, as active ingredient, a compound of the general formula ##STR1## in which each of n and m independently is 0 or 1; each of Ar.sup.1 and Ar.sup.2 independently is an aryl group, at least one of Ar.sup.1 and Ar.sup.2 being substituted by one or more of the same or different substituents selected from halogen atoms, alkyl groups, alkoxy groups, haloalkyl groups and haloalkoxy groups; and R.sup.1 is hydrogen, or an alkyl, alkylthio or haloalkyl group having from 1 to 4 carbon atoms, and R.sup.2 is hydrogen or a halogen atom provided that at least one of R.sup.1 and R.sup.2 represents a hydrogen atom. Certain compounds of formula I are novel.

Herbicidal 2,6-substituted pyridines

Compounds of the formula: ##STR1## wherein R.sup.1 is hydrogen or alkyl;

Pesticidal compounds

Compounds of the formula ##STR1## wherein X.sup.1, X.sup.2 and X.sup.3 each independently represents hydrogen, halogen or alkyl; n is 0 or 1; Z represents hydrogen or halogen or an amino, alkyl, haloalkyl, alkylthio or alkoxy group or a phenoxy group optionally substituted by haloalkyl; A represents CH or N; Y.sup.1 and ZY.sup.2 each independently represents hydrogen, halogen, alkyl, haloalkyl, alkoxy or haloalkoxy; and W represents hydrogen or, when A is CH and at least one of Y.sup.1 and Y.sup.2 is not hydrogen or when A is N, hydrogen or halogen; with the proviso that when A represents N, then each of Y.sup.1 and Y.sup.2 represents hydrogen, have herbicidal properties. The invention also provides a process for their preparation and their use as herbicides.

Herbicidal compounds

Compounds of formula ##STR1## in which X is nitro;

A novel herbicide of formula I ##STR1## wherein R.sub.1 represents a halogen atom or an alkyl, haloalkoxy, haloalkyl or alkoxycarbonyl group;

Anilide herbicides

Compounds of the formula ##STR1## wherein the symbols have assigned meanings, and their use as herbicides.
