Plant growth regulating compounds are N-substituted-P-(2-chloroethyl)-phosphonamidic esters of the formula: ##EQU1## wherein R is cycloalkyl, R.sub.1 is hydrogen or cycloalkyl or R and R.sub.1 together form a heterocyclic ring such as morpholine, piperidine or pyrrolidine and R.sub.2 is alkyl or haloalkyl. They are prepared by the reaction of 2-chloroethylphosphonohalidic esters with the appropriate secondary amine.
植物生长调节剂是公式为:##EQU1##的N-取代-P-(2-氯乙基)-磷酰胺酯化合物,其中R为环烷基,R.sub.1为氢或环烷基或R和R.sub.1共同形成杂环环,如吗啡啉、哌啶或吡咯啉,R.sub.2为烷基或卤代烷基。它们是通过2-氯乙基磷酸酯与适当的二级胺反应制备的。
