标题 :Synthesis of sulfilimines
发明人：GETMAN DANIEL P
权利人:MONSANTO CO
摘要:Processes are disclosed for preparation of N-aryl-S,S-dihydrocarbylsulfilimines by reaction of phenylisocyanate compounds with hydrocarbyl sulfoxides. The sulfilimines can be rearranged to ortho-thioalkylene anilines and the reactions can be employed in a route for converting nitrobenzene compounds to ortho-thioalkylene anilines, which are useful intermediates for preparation of herbicidal compounds.

标 题:Nucleophilic substitution process
发明人：STAHLY G PATRICK; STAHLY BARBARA C
权利人:ETHYL CORP
摘要:Nitroarylacetic acid esters are prepared by reacting a nitroaromatic compound which is devoid of halogen on the aromatic ring carrying a nitro group with an alpha,alpha-disubstituted acetic acid ester in an inert solvent and in the presence of a base so that the ester undergoes a nucleophilic substitution on an unsubstituted ring carbon of the nitroaromatic compound during which an alpha-substituent functions as a leaving group. Nitrobenzene acetic acids and their esters are useful intermediates for the synthesis of pharmaceuticals.

摘要:A process for the preparation of compounds containing a difluoromethylene or trifluoromethyl group. A compound containing a carbonyl group, preferbly an acid, acid halide, amide, ketone or any compound containing a perhaloalkylcarbonyl moiety is placed, in anhydrous liquid hydrofluoric acid, in contact with boron trifluoride in a quantity such that the absolute pressure of boron trifluoride in the reaction system is at least one bar for a time sufficient to convert the carbonyl group to a difluormethylene or trifluoromethyl group. n The compounds obtained are useful as synthesis intermediates in the pharmaceutical, plant-protection and dye industries, as anesthetics or as heat-transfer and lubricating fluids.
