ABSTRACT:

The invention relates to novel substituted heterocycloalkenes, to a number of processes for their preparation and to their use as fungicides, and to novel intermediates and to a number of processes for their preparation.
It is known that certain substituted heterocyclic compounds possess fungicidal properties (cf. e.g. WO-A 9422844). However, the action of these compounds, especially at low application rates, is not entirely satisfactory in all areas of application.
The novel substituted heterocycloalkenes have now been found of the general formula (I)
in which
A represents optionally substituted alkylene,
Ar represents optionally substituted arylene or heteroarylene,
E represents a 1-alkene-1,1-diyl grouping which in position 2 contains a radical R
1
, or represents a 2-aza-1-alkene-1,1-diyl grouping which in position 2 contains a radical R
2
, or represents an optionally substituted imino grouping (“azamethylene”, N-R
3
), or represents a 3-aza-1-propene-2,3-diyl grouping which contains in position 1 a radical R
1
and in position 3 a radical R
3
, or represents a 3-oxa-1-propene-2,3-diyl grouping which contains in position 1 a radical R
1
, or represents a 3-thia-1-propene-2,3-diyl grouping which contains in position 1 a radical R
1
, or represents a 1-aza-1-propene-2,3-diyl grouping which contains in position 1 a radical R
2
and in position 3 a radical R
3
, or represents a 1-aza-1-propene-2,3-diyl grouping which contains in position 1 a radical R
1
and in position 3 a radical R
3
, or represents a 1,3-diaza-1-propene-2,3-diyl grouping which contains in position 1 a radical R
2
and in position 3 a radical R
3
or represents a 1-aza-3-oxa-1-propene-2,3-diyl grouping which contains in position 1 a radical R
2

Aryl represents aromatic, mono- or polycyclic hydrocarbon rings, for example phenyl, naphthyl, anthryl, phenanthryl, preferably phenyl or naphthyl, especially phenyl.
Heterocyclyl represents saturated or unsaturated, and aromatic, cyclic compounds in which at least one ring member is a heteroatom, i.e. an atom other than carbon. If the ring comprises two or more heteroatoms, they can be identical or different. Heteroatoms are preferably oxygen, nitrogen or sulphur. The cyclic compounds may form a polycyclic ring system together with further carbocyclic or heterocyclic, fused-on or bridge-connected rings. Preferred systems are mono- or bicyclic ring systems, especially mono- or bicyclic aromatic ring systems.
It has also been found that the novel substituted heterocycloalkenes of the general formula (I) are obtained if
a) hydroxyl compounds of the general formula (II)

Finally it has been found that the novel substituted heterocycloalkenes of the general formula (I) show a very strong fungicidal action.
The compounds according to the invention can if appropriate be present as mixtures of different possible isomeric forms, especially of stereoisomers, for example E and Z isomers, if appropriate also of tautomers. The claimed subject-matter comprises both the E isomers and the Z isomers, any desired mixtures of these isomers, and the possible tautomeric forms.
