Benzyl Carbazate is available in 25 kg conta
The present invention relates to a process for preparing optionally substituted benzyl carbazates of formula wherein each R1 independently represents C1 -C4 -alkyl, C1 -C4 -alkoxy, di(C1 -C4 -alkyl)amino, nitro, halogen, hydroxyl, the group X-R3, wherein X represents O or S and R3 represents straight-chain or branched C1 -C4 -alkyl, the group COOR4, wherein R4 represents C1 -C4 -alkyl, the group NR5 R6, wherein R5 and R6 independently represent C1 -C4 -alkyl, or a C3 -C6 -cycloalkyl group that is optionally substituted by straight-chain or branched C1 -C4 -alkyl groups, and n is an integer from 0 to 5,by reacting a dialkyl carbonate with an optionally substituted benzyl alcohol in the presence of a catalyst, separating off the resulting reaction mixture from the catalyst, and subsequently reacting the separated reaction mixture with hydrazine hydrate.Benzyl carbazate is a synthetic organic chemical compound used as an intermediate in the manufacture of a broad spectrum insecticide. When formulated into finished products these insecticidal formulations are used to control the target lepidoptera pests on cotton, vegetables, and fruits. These
products are efficacious in control of target pests while preserving beneficial
insecs and mites, have a favorable environmental profile, relatively short half
life, low environmental loading, and large margin of safety to mammalian,
avian, aquatic, and non-target organisms. Their novel mode-of-action results
in a lack of cross resistance to standard insect control compounds and
consequently is well suited for integrated pest management (IPM) programs.
the Commission recommends that the chemical name in HTS heading
9902.29.96 be amended by inserting the European Inventory name ìbenzyl carbazateî for further identification.
