Azolyl-tetrahydrofuran-2-ylidene-methanes of the formula ##STR1## in which A represents a nitrogen atom or the CH group; X represents oxygen, sulphur or the SO or SO.sub.2 group; R represents optionally substituted aryl; R.sup.1 and R.sup.6 are identical or different and represent hydrogen, alkyl, halogenoalkyl or halogen, a maximum of up to 3 substituents representing halogen or halogenoalkyl, with the proviso that R.sup.1 and R.sup.2 are not at the same time methyl if X represents oxygen; R.sup.1 and R.sup.2, together with the carbon atom to which they are bonded, represent optionally substituted cycloalkyl or R.sup.2 and R.sup.3, together with the carbon atoms to which they are bonded, represent optionally substituted cycloalkyl, or addition products thereof with acids or metal salts. Some new intermediates are also shown. The end products are fungicides.
公式为 ##STR1## 的Azolyl-tetrahydrofuran-2-ylidene-methanes,其中A代表氮原子或CH基团;X代表氧、
硫或SO或SO.sub.2基团;R代表可选取代的芳基;R.sup.1和R.sup.6相同或不同,代表氢、烷基、卤代烷基或卤素,最多可有3个卤素或卤代烷基取代基,但如果X代表氧,则R.sup.1和R.sup.2不能同时为甲基;R.sup.1和R.sup.2与它们所连接的碳原子一起,代表可选取代的环烷基,或R.sup.2和R.sup.3与它们所连接的碳原子一起,代表可选取代的环烷基,或它们与酸或
金属盐的加成物。一些新的中间体也被展示。最终产品是杀真菌剂。
