The invention relates to new plant growth regulating compositions, which contain as active agent 0.001 to 95% by weight of one or more compound(s) of the general formula (I), ##STR1## wherein R.sup.1 and R.sup.2 each represent hydrogen atom, a C.sub.1-5 alkyl group, a C.sub.5-7 cycloalkyl group, an aryl group, a halogen-substituted aryl group, an aralkyl group, a C.sub.2-5 alkenyl group or a C.sub.2-5 alkynyl group, or R.sup.1 and R.sup.2 form, together with the adjacent nitrogen atom, a morpholino, pyrrolidino, piperidino or perhydroazepinyl group, and R.sup.3 stands for hydrogen or a C.sub.1-5 alkyl group, together with an inert, solid, liquid and/or gaseous carrier or diluent, and optionally one or more additives, such as surfactants or other substances of plant biological activity. The compounds of the general formula (I) in which R.sup.1 is hydrogen and R.sup.2 stands for hydrogen, C.sub.1-3 alkyl, aralkyl or C.sub.3-5 alkenyl group, furthermore in which R.sup.1 and R.sup.3 are hydrogen and R.sup.2 is an aryl group have already been described in the literature, whereas the remaining derivatives of the general formula (I) are new. These compounds can be prepared by reacting a compound of the general formula (II) ##STR2## with an amine of the general formula (III), ##STR3## or by alkylating a compound of the general formula (IV). ##STR4## In the above formulae X stands for halogen, hydroxy or C.sub.1-4 alkoxy, whereas R.sup.1, R.sup.2 and R.sup.3 have the meanings as defined above.
本发明涉及一种新的植物生长调节组合物,其含有作为活性剂的一种或多种化合物,其重量百分比为0.001至95%,所述化合物的一般式(I)如下:##STR1## 其中R.sup.1和R.sup.2分别表示氢原子,C.sub.1-5烷基,C.sub.5-7环烷基,芳基,卤代芳基,芳基烷基,C.sub.2-5烯基或C.sub.2-5炔基,或者R.sup.1和R.sup.2与相邻的氮原子一起形成吗啉基,吡咯烷基,哌啶基或过氢杂环庚烷基,而R.sup.3代表氢或C.sub.1-5烷基,与惰性的固体,液体和/或气体载体或稀释剂以及可选的一种或多种添加剂,如表面活性剂或其他植物生物活性物质相结合。已经在文献中描述了其中R.sup.1为氢,R.sup.2为氢,C.sub.1-3烷基,芳基烷基或C.sub.3-5烯基的一般式(I)化合物,而R.sup.1和R.sup.3为氢,R.sup.2为芳基的剩余衍生物是新的。这些化合物可以通过将一般式(II)化合物与一般式(III)胺反应,或通过烷基化一般式(IV)化合物来制备。##STR2## 在上述公式中,X表示卤素,羟基或C.sub.1-4烷氧基,而R.sup.1,R.sup.2和R.sup.3具有上述定义的含义。
