Matsuda–Heck reaction with arenediazonium tosylates in water
An environmentally friendly Matsuda-Heck reaction with arenediazonium tosylates has been developed for the first time. A range of alkenes was arylated in good to quantitative yields in water. The reaction is significantly accelerated when carried out under microwave heating. The arylation of haloalkylacrylates with diazonium salts has been implemented for the first time.
متن کاملHeck reaction of arenediazonium salts with N,N-diprotected allylamines. Synthesis of cinnamylamines and indoles.
Novel palladium-catalyzed reactions of arenediazonium tetrafluoroborates with N,N-diprotected allylamines are presented. The reaction of arenediazonium tetrafluoroborates with N,N-(Boc)(2) allylamine allows for an easy approach to cinnamylamines whereas using 2-alkynyl-N-(allyl)trifluoroacetanilides and 2-iodo-N-(allyl)trifluoroacetanilide the reaction provides a useful tool for appending indol...
متن کاملIridium-Catalyzed ortho-Arylation of Benzoic Acids with Arenediazonium Salts.
In the presence of catalytic [{IrCp*Cl2 }2 ] and Ag2 CO3 , Li2 CO3 as the base, and acetone as the solvent, benzoic acids react with arenediazonium salts to give the corresponding diaryl-2-carboxylates under mild conditions. This C-H arylation process is generally applicable to diversely substituted substrates, ranging from extremely electron-rich to electron-poor derivatives. The carboxylate d...
متن کاملPalladium-catalyzed Sonogashira reactions of aryl amines with alkynes via in situ formation of arenediazonium salts.
A general and convenient palladium-catalyzed Sonogashira reaction of in situ generated arenediazonium salts has been developed and various internal arylalkynes are produced in good yields under mild conditions.
متن کاملTrifluoromethylation of arenediazonium salts with fluoroform-derived CuCF3 in aqueous media.
A new protocol has been developed for trifluoromethylation of arenediazonium salts with moisture-sensitive CuCF3 (from fluoroform) in aqueous media. The reaction is governed by a radical mechanism, tolerates a broad variety of functional groups, and is applicable to the synthesis of complex, polyfunctionalized molecules.
