摘要：NOVELTY - This invention relates to triazolacylamine compound containing selenium and its preparation and use. It is prepared by: using substituted amine as start material, preparing its diazo salt, making thesaid salt condensed with triazoselenophen to obtain aromatic triazoselenide, oxidizing it to obtain triazoselesulfoxide (triazosulfone), condensing triazo sulfone and sulfoxide and aromatic triazoselenide with N,N dialkyl formyl chloride selectively to obtain target products; or oxidizing triazoselenide with dioxide to obtain triazo selenic acid, then preparing Cl selenide, condensing it with substituted phenol to obtain selenonyl triazophenate, condensing it with N,N dialkyl formyl chloride to obtain target product. It can be used as herbicide for crop with good selective ability and safety.
