Compounds are prepared which correspond to the formula ##STR1## wherein R represents hydrogen, chloro, bromo or trifluoromethyl; n represents an integer of from 1 or 2 with the proviso that when R is trifluoromethyl, n is 1; R.sup.1, R.sup.2 and R.sup.3 each independently represent ethyl, n-propyl, n-butyl, isobutyl, ethynyl, vinyl or ethoxymethyl or R.sup.2 and R.sup.3 taken together form an alkylene bridge of 2 to 4 carbon atoms and X represents a non-phytotoxic anion. The compounds have been found to be active plant growth regulatory control agents.
制备与以下公式对应的化合物##STR1##其中R代表氢、氯、溴或三氟甲基;n表示1或2的整数,但当R为三氟甲基时,n为1;R.sup.1、R.sup.2和R.sup.3分别独立地代表乙基、正丙基、正丁基、异丁基、乙炔基、乙烯基或乙氧甲基,或R.sup.2和R.sup.3一起形成2到4个碳原子的烷基桥,X代表非植物毒性的阴离子。已发现这些化合物是活性植物生长调节控制剂。
