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-l-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.

Also, a catalyst having the structure or its enantiomer: (II) wherein: each one of Ra, Rb, Rc and Rd is selected from alkyl, cycloalkyl, and aryl; the bridge group is selected from CH2NH; *CH(CH3)NH(C*,R); and *CH(CH3)NH(C*,S); the organocatalyst is an organic molecule catalyst covalently bound to the bridge group; and M is selected from the group consisting of Rh, Pd, Cu, Ru, Ir, Ag, Au, Zn, Ni, Co, and Fe.
摘要:
A method for producing a β-nitrostyrene compound is provided in which a benzaldehyde derivative represented by the following formula (I): and nitromethane are condensed in an acetic acid solvent in the presence of a primary amine. This method allows production of a β-nitrostyrene compound at a high yield in the industrially-safe reaction temperature range.
