Their physical constants, UV, IR, 1H NMR and elementary analysis were originally characterized, biological activity were originally studied. It is found from the results of biological activity tests that some compounds have a remarkable activity on plant growth hormone. Compounds Ⅲa and Ⅲk have a good activity on cytokinin, compounds Ⅲe and Ⅲj and Ⅲl have an excellent activity on auxin.展开更多
Seven novel N-(5-tetrazolyl) -N-(aryloxyacetyl)ureas have been synthesized by the additive reaction of 5-amino-1H-1,2,3,4-tetrazole with aryloxyacetyl isocyanate. Their structures were confirmed by IR, 1H NMR and el...Seven novel N-(5-tetrazolyl) -N-(aryloxyacetyl)ureas have been synthesized by the additive reaction of 5-amino-1H-1,2,3,4-tetrazole with aryloxyacetyl isocyanate. Their structures were confirmed by IR, 1H NMR and elemental analysis. The biological activity tests show the target compounds have a good activity as plant growth regulator, and N-(5-tetrazolyl)-N-(3-chlorophenyloxyacetyl)-urea and N-(5-tetrazolyl)-N-(1-naphthyloxyacetyl)-urea have a activity close to cytokinin.展开更多
