โœฆ Synopsis

In order to search for novel herbicides with high activity and selectivity, a series of thio(seleno) phosphate-phosphonate derivatives were synthesized in good yields by a one-pot procedure using tris(diethylamino)phosphine activated by iodine as the phosphorylating reagent. The structures of all compounds prepared were confirmed by spectroscopic methods and microanalyses. Preliminary bioassays indicated that some of the products possess potent and selective herbicidal activities and antiphytoviral activities against the tobacco mosaic virus (TMV). In addition, some of them exhibit significant fungicidal ac-

## Abstract A series of novel (thio)ureas containing the pyrimidinyl group was designed and synthesized. Their __inโ€vitro__ antitumor activity against different human tumor cells was examined. Some of the compounds showed potential antitumor activity, which provided some hints for further studies o
