HETEROCYCLIC SUBSTITUTED AZOLES AND AZINES
AND THEIR USE AS HERBICIDES
Description
This invention relates to new substituted asoles and ezines, processes for their preparation and their use as herbicides.
It is §nown that certain triawmolopyridiazine and bensothiasolylazolidines possess herbicidal amotivity (BP applications O 176 101 and 0 230 874). However the herbicidal activity of these known compounds is not al- ways sufficient or selectivity problems can occur in im- portant orops.
The object of the present invention is to make nev compounds that do not show these disadvantages and have improved biological properties over the known com- pounds,
It has now been found that heterocyclic substituted asoles and asines of general formulas I

The expression "halogen'! means fluorine, ohlo- rine, bromine and iodine. The term "haloalkyl" means that one or more hydrogen atoms of the alkyl are re- placed by halogen.
Examples of heterocyclic rings are pyrrole, oxa- sole, thiazole, imidazole, pyridine, oxazine, thiazine, pyrimidine, pyrasine, trissine, oxadiarine and thiadie- sines well as their di- , tetra- or preferably hexahydro ’ ’ derivatives.

The reaction time is between 1 to 24 hours. Uenerally, the react- fon is carried out in the presence of en acid, such as for exemple acetic, where the acetic acid for ex- ample can also act as solvent, It is however also pos- sible to react both reactahts using an inert solvent, such as for example dichloromethane or dimethyl sulpho- xide, and to cyclise the resulting intermediate addition product with an acid anhydride, such as for example ace- tic anhydride.
The reaction according to process variant B) is 20 . generally carried out in three stages without interme- diate purification of the products, according to the following renction scheme:

An improvement in the intensity and speed of action can be obtained, for example, by addition of suitable ad- juvants, such as organic solvents, wetting agents and oiln.
Such additives may allow a desrense in the dose.
Suitable mixture partners may include phospholipids, " e.g. phosphatidyloholine, hydrogenated phosphatiiiyloholines phosphatidylethanolamines, N-aoyl-phoasphatidylethanclamines, phosphatidylinositol, phosphatidylserine, lysolecithin or - % =

Suitable solid carriers include mineral earths, e.g. bentonite, silica gel, taloum, kaolin, attapulgite, limestone, silicic acid and plant -products, e.g. flours.
As surface-active agents there can be used for example calcium lignosulphonate, polyoxyethylenealkyl- phenyl ethers, naphthalenosulphonic acids and their salts, 7 Phenolsulphonic acids and their salts, formsldehyde conden- sates, fatty alcohol sulphates, as well as substituted bens senessulphonic acide and their salts.

I1Ye cent by weight liquid or solid carriers, as well as, optionally up to 20 percent by weight or sur- factant.
The agents can be applied in customary fashion, for example with Vater as the carrier in spray mix- ture volumes of approximately 100 to 1,000 1/ha. The agents can be applied using low-volume of ultra-low- volume techniques or in the form of so-called micro- granules. . 5, . J
