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
