Amino Alcohols as Ligands for Nickel-Catalyzed Suzuki Reactions of Unactivated Alkyl Halides, Including Secondary Alkyl Chlorides, with Arylboronic Acids

Abstract: Suzuki cross-coupling reactions of an unprecedented array of unactivated primary and secondary alkyl halides (including challenging alkyl chlorides) can be accomplished through the use of nickel/amino alcohol-based catalysts. Both the nickel precatalyst and the amino alcohols (prolinol or trans-2-aminocyclohexanol) are commercially available and air-stable. In view of the remarkable diversity of amino alcohols that are readily accessible, this discovery may open the door to the rapid development of versatile c… Show more

“…Nach dem bahnbrechenden Beitrag von Suzuki et al aus dem Jahr 1992 [7] gen ausführen ließ. [15] Mit dem Katalysatorsystem NiI 2 /2-Aminocyclohexanol konnten nichtaktivierte und funktionalisierte cyclische und acyclische sekundäre Alkylbromide und -iodide gekuppelt werden; es waren auch ortho-Substituenten an der Boronsäure möglich (Schema 7 a). Ein leicht verän-derter Katalysator -aus NiCl 2 und Prolinol -ermöglichte die erste Suzuki-Kupplung von nichtaktivierten sekundären Alkylchloriden (Schema 7 b).…”
