Aryl Grignard Reagents (aryl + grignard_reagent)
Selected AbstractsPractical Iron-Catalyzed Allylations of Aryl Grignard ReagentsADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 13 2010Matthias Mayer Abstract An operationally simple iron-catalyzed reductive cross-coupling reaction between aryl halides and allyl electrophiles has been developed. The underlying domino process exhibits high versatility with respect to the allylic leaving group (acetate, tosylate, diethyl phosphate, methyl carbonate, trimethylsilanolate, methanethiolate, chloride, bromide) and high economic and environmental sustainability with respect to the catalyst system (0.2,5 mol% tris(acetylacetonato)iron(III), ligand-free) and reaction conditions (tetrahydrofuran, 0,°C, 45,min).

Mit einer neuen, allgemein verwendbaren Strategie gelingt die Titelreaktion (siehe Schema; NMP=N -Methylpyrrolidinon). Die Reaktion ist chemoselektiv und ermöglicht die Synthese einer Vielzahl einfacher und funktionalisierter interner Alkine in hohen Ausbeuten.
