Studies on the Synthesis and Biological Activity of N-Substituted Phenoxyacetyl-N'-Pyrimidinylthioureas Zhang Bin, Chen Zhiqiong#, Chen Yong, Wan Ping, Chen Shulian (Department of Applied Oil Engineering, Logistical Engineering Univeristy, Chongqing 40016) (# Department of Chemistry, Chongqing University of Medical Sciences, Chongqing 400016) Abstract Eight new N-substituted phenoxyacetyl-N'-pyrimidinylthioureas were synthesized. Their structures were confirmed by elemental analysis and 1H NMR, some were identified by IR and MS. The preliminary biological activity tests showed that some of the compounds have good herbicidal activity and plant growth regulation function.
