Process for producing chloromethylphenylacetic acid

A condensed heterocyclic derivative of the formula ##STR1## (wherein R is a hydroxyl group, R.sup.3 or R.sup.4 is an alkoxy group, W is an oxygen atom, Yn is a hydrogen atom, Z is a methine group, and A is a 5- or 6-membered heterocyclic ring which may be substituted, and a herbicide, are presented. When used for paddy field treatment, upland soil treatment and foliage treatment, the condensed heterocyclic derivative of the present invention exhibits excellent herbicidal activities against gramineous and non-gramineous weeds without adversely affecting crop plants.

The present invention provides a novel pyridine derivative having the following general formula and its salt: ##STR1## wherein R is a hydrogen atom, a hydroxyl group, an alkoxy group, an alkoxyalkoxy group, and derivatives;

Pyridine derivatives, herbicidal composition containing the same, and

As new compound is provided a cyclohexane derivative of the formula ##STR1## wherein R.sup.1 is a hydrogen or a lower alkyl; R.sup.2 is a lower alkyl; R.sup.3 is a hydrogen, an alkyl, an alkenyl, a hydroxyalkyl, a cycloalkyl, a morpholino, an aminoalkyl, an N-alkylaminoalkyl, an N,N-di-alkylaminoalkyl, an alkoxycarbonylalkyl, a group of the formula --(CH.sub.2).sub.l --R.sup.4 where R.sup.4 is a lower alkoxy, a lower alkylthio, a benzylthio, an anilino, a morpholino, a piperazino, a piperidino or a lower alkyl-substituted piperidino and l is 2 or 3, a group of the formula ##STR2## where X is a halogen, a lower alkyl, a lower alkoxy, a phenoxy or an alkoxycarbonylalkyloxy, m is zero or 1 and n is an integer of zero to 2, inclusive, a group of the formula --CH.sub.2 --R.sup.5 where R.sup.5 is a furyl, a thenyl or a pyridyl, or a group of the formula ##STR3## where R.sup.5 is as defined above; or a salt of said cyclohexane derivative. This cyclohexane derivative exhibits useful plant growth regulating effects on crop-plants and also non-crop-plant such as lawn.

Cyclohexane derivatives having plant growth regulating activities and

A new compound is provided by a cyclohexane derivative of the formula ##STR1## wherein R represents a hydrogen atom or an alkyl group, an alkylthioalkyl group or an unsubstituted or substituted phenyl group; and R.sup.1 represents an alkyl group, an unsubstituted or substituted benzyl group, a phenethyl group, a phenoxymethyl group, a 2-thienylmethyl group, an alkoxymethyl group or an alkylthiomethyl group, or a salt of said cyclohexane compound. This cyclohexane compound exhibits useful plant-growth regulating effects on crop-plants and also non-crop plants such as lawn and may be prepared by cyclization of an acetonylsuccinic acid dialkyl ester, followed by reaction with an organic acid chloride and by intermolecular rearrangement.
