Nikonorov等人曾报道N＇-烃基磷酰脲类化合物具有良好的除草活性,但对N＇-芳酰基磷酰脲类衍生物尚未见报道。前文曾报道此类化合物的先导母体化合物[(RO)_2P(X)-NHCONHCOC_6H_5]的合成和对乙酰胆碱酯酶(AChE)的抑制活性。为了进一步研究这类化

Sixteen N-(O, O-dialkylthiophosphoryl)N＇-(4-Chlorobenzoyl) ureas (1a~h) and N- (O, O-dialkylphosphoryl)-N＇- (4-Chlorobenzoyl) ureas (2a~h) were synthesized by nucleo- philic addition of (thio)phosphoramide to 4-chlorobenzoyl isocyanate. The structure of all the title compounds were characterized by elemenal analyses, IR, 1~H NMR (31)~p NMR. The ...
