| Abstract | Disclosed is an improved method for producing a nitroisourea derivative which is necessary for producing a nitroguanidine derivative having an insecticidal activity. Specifically disclosed is a method for producing a nitroisourea derivative represented by the general formula (3) below, which is characterized in that a nitroisourea represented by the general formula (1) below and an amine represented by the general formula (2) below or a salt thereof are reacted in the co-presence of a catalytic amount of a hydrogen carbonate.
La présente invention concerne un procédé amélioré de production d'un dérivé de nitro-iso-urée qui est nécessaire pour produire un dérivé de nitroguanidine possédant une activité insecticide. Cette invention concerne plus spécifiquement un procédé de production d'un dérivé de nirto-iso-urée représenté par la formule générale (3) ci-dessous, qui se caractérise en ce qu'un composé nitro-iso-urée représenté par la formule générale (1) ci-dessous et un amine représenté par la formule générale (2) ci-dessous ou un sel de celui-ci réagissent en présence d'une quantité catalytique d'un carbonate d'hydrogène. |
