SYNTHESIS AND HERBICIDAL ACTIVITIES OF (E) O AROYL α OXOCYCLODODECANONE OXIMES

Nine (E) O aroyl α oxocyclododecanone oxime(V1 V9) were synthesized from cyclododecanone: ZJLX,YS;X O CH 3ONO0-5℃ ZJLX,YS;X O ZJLX,YX;Z N OH IV ArCOOH,DCC/CH 2Cl 2R.T. ZJLX,YS;X O ZJLX,YX;Z N OCO Ar V Their structures were confirmed by IR, 1HNMR and elemental analysis. The bioassay of all the title compounds was carried out. The results showed that some of them possess herbicidal activities, among them V3 has good herbicidal activities. (E) configuration of α oxocyclododecanone oxime was confirmed by its Beckmann reaction which gives 11 cyanoundodecanoic acid.
