摘要:
The present invention relates to a process for preparing substituted 2-nitrobiphenyls and to specific 2-nitrobiphenyls. The invention further relates to a process for preparing 2-aminobiphenyls from such 2-nitrobiphenyls and to a process for preparing (het)arylamides of such 2-aminobiphenyls.
摘要:
An optically active nitro compound having two hydrogen atoms on its α-carbon atom and having β-asymmetric carbon atom can be produced by making α,β-unsaturated nitroolefin having a hydrogen atom on its α-carbon atom react with at least two organosilicon compounds having at least one silicon-hydrogen bond in the molecule in the presence of an asymmetric copper complex, or react with an organosilicon compound having at least one silicon-hydrogen bond in the molecule in the presence of an asymmetric copper complex and water.
摘要:
Fluorinated alkene compounds useful for and methods of controlling nematodes, insects, and acarids that prey on agricultural crops. Polar compounds, for example, 3,4,4-trifluoro-3-butene-1-amine or 3,4,4-trifluoro-3-butenoic acid, are particularly useful for systemic control of pests. Novel method and intermediates for the preparation of 3,4,4-trifluoro-3-butene-1-amine are also provided.
