[N-acylindoline with phytotoxic activity. I].
A series of N-acyl derivatives of indoline (A) was prepared and tested for phytotoxic activity. The substances studied (Tables I leads to III, substances I leads to XXVIII) were prepared by reaction of indoline with suitable acylating agents and were mainly new compounds. The biological tests consisted in pre- and post-emergence treatment in doses of 6 kg/ha or lower doses on five common weeds; one substance (XXV) was tested also on other species of economic importance (Table III). The results show that of the three classes studied the N-carbamoyl- and N-thiocarbamoyl derivatives of indoline have wide spectrum phytotoxic activity especialy on absorption via the foliage. The highest phytotoxic activity in both pre- and post-emergence tests was shown by N-(methylcarbamoyl)indoline (XIII) and N-(dimethylcarbamoyl(indoline (XXIII).
