Compounds having blood-anticoagulant properties of the general molecular formula: ##STR1## in which Z represents a halogen atom, preferably a chlorine atom, and n is 0, 1 or 2 and R.sup.4 represents either (1) a grouping which comprises a phenylene radical attached directly or indirectly to the tetralin ring and having in the para position (with respect to such attachment) an electron-withdrawing atom or group whose rotational volume substantially does not exceed that of a phenyl group and which forms together with said phenylene radical a polarizable structure, or (2) a grouping selected from: ##STR2## or (3) a grouping which comprises a phenylene radical attached directly to the tetralin ring and having in the para position (with respect to such attachment) a substituted furanyl or thiophenyl radical attached thereto directly or through oxygen and/or methylene, said furanyl or thiophenyl radical having such an electron-withdrawing atom or group as a substituent in a position forming with the furanyl or thiophenyl radical a polarizable structure, compounds of the type (1) in which R.sup.4 contains two phenylene radicals linked essentially linearly by an aliphatic chain comprising a methylene radical or radicals and optionally at least one oxygen or sulphur atom being preferred. Also included are the processes for the preparation of such compound; rodenticidal compositions containing them; and a method for controlling rodents by applying such a composition.
具有一般分子式的抗凝血性质的化合物:##STR1## 其中Z代表卤素原子,最好是氯原子,n为0、1或2,R.sup.4表示(1)一个包含苯基团,直接或间接连接到四氢萘环上,并在对位(相对于该连接)具有一个电子吸引原子或基团,其旋转体积基本上不超过苯基团的大小,并且与所述苯基团一起形成一个可极化结构,或(2)从以下选定的一个组合:##STR2## 或(3)一个包含苯基团的组合,直接连接到四氢萘环上,并在对位(相对于该连接)具有一个取代的呋喃基或噻吩基团,直接或通过氧和/或亚甲基连接到其中,所述呋喃基或噻吩基团具有一个电子吸引原子或基团作为取代基,形成与呋喃基或噻吩基团一起的可极化结构,首选含有两个苯基团的化合物(1),这两个苯基团通过一个亚硫酸基团或基团基本上线性连接,且可能至少包含一个氧或硫原子。还包括制备这种化合物的过程;含有它们的杀鼠剂组合物;以及通过应用这种组合物来控制啮齿动物的方法。
