A compound is disclosed having the formula: ##STR1## The compound is useful as an active ingredient in a herbicidal composition.

Herbicidal 6-thienyloxypyrid-2-carboxamides

Herbicidal thienyloxyazines

New herbicidal pyridine and pyrimidine derivatives of general formula (I), ##STR1## wherein Z represents a nitrogen atom or a C--H group; A represents an optionally substituted aryl group or an optionally substituted 5- or 6-membered nitrogen-containing heteroaromatic group; n represents an integer from 0 to 2 and R.sup.1 or each R.sup.1 independently represents a hydrogen atom or an optionally substituted alkyl, alkoxy, alkylthio or dialkylamino group; m represents an integer from 0 to 5 and R.sup.2 or each R.sup.2 independently represents a hydrogen or a halogen atom or an optionally substituted alkyl, haloalkyl, haloalkoxy, alkoxy, alkylthio group or a nitro, cyano or a halosulphonyl group; and X represents an oxygen or sulphur atom.

Herbicidal 2-(hectero)aryloxy-6-arypyridines and

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

There are prepared compounds of the formula ##STR1## where &gt;A--B-- has either the structure &gt;C(OH)--CH.sub.2 -- or the structure &gt;C.dbd.CH, Alk is a straight or branched chain C.sub.1 -C.sub.5 - alkylene group and -NHY is ##STR2## where R' is hydrogen, phenyl, phenyl substituted once or twice by C.sub.1 -C.sub.4 -alkyl groups, a C.sub.1 -C.sub.4 -alkoxy group or by halogen atoms, a C.sub.1 -C.sub.6 -alkyl group, a C.sub.1 -C.sub.4 -hydroxyalkyl group or a phenalkyl group whose alkyl portion consists of 1-4 carbon atoms or such a phenalkyl group containing 1 to 3 C.sub.1 -C.sub.4 -alkoxy group substituents. The compounds are effective in improving peripheral and cerebral circulation. There are also produced intermediate compounds of formula (II) where NHY is replaced by chlorine, bromine or iodine.

Dithienylalkylamines and process for their production

Pyridines substituted in the 2- and 6-positions by an aromatic or heteroaromatic group are prepared by reacting an aromatic or heteroaromatic ketone having at least one reactive methylene group adjacent to the keto group with an aliphatic aldehyde and ammonia in the presence of a dehydrating and dehydrogenating catalyst at a temperature of about 250.degree. to 550.degree. C.
