Novel stereoselective alkenyl–aryl coupling via nickel-catalysed reaction of alkenylanes with aryl halides

Abstract: Summmvy trans-Alkenylalanes, readily obtainable via of nickel complexes, such as tetrakis( triphenylphosphine) -nickel, to produce arylated alkenes in high yields, the stereochemistry of the products being >99% trans. hydroaluminiation of acetylenes, react readily with aryl bromides and iodides in the presence of catalytic amounts

“…[ [72] Sekiya, [73] Dang [74] und Negishi. [76] Allerdings verlief die Synthese konjugierter Diene über Organoaluminiumreagentien in manchen Fällen alles andere als stereospezifisch. Murahashi gelang auch dies, allerdings erst 1979 in katalytischer Weise.…”

“…Die Selektivitätssteigerung wurde allerdings dadurch erkauft, dass die palladiumkatalysierten Protokolle nur auf die reaktiveren Arylbromide und -iodide anwendbar waren, nicht aber auf Arylchloride. [76][77][78] Tabelle 1: Kupplungen von Zink-, Bor-und Zinnacetyliden mit einem Aryliodid. Aber wie so oft in den folgenden Jahren verdrängte Palladium das Nickel auch hierbei, weil seine Reaktivität unter Beibehaltung der besseren Selektivität durch den Einsatz von Liganden gesteigert werden konnte.…”

“…In fact, there were several other organometallics that were utilised by the Negishi school before zinc (for example , aluminium, zirconium and boron) (5761). The synthetic potential of zinc reagents, RZnX, however, is undeniable, as they possess a suitable level of nucleophilicity to participate in a transmetalation step to a Pd(II) intermediate, while being especially tolerant of most functionality (62).…”

“…Also the use of reagents in a catalytic fashion is highly attractive for increasing efficiency of synthetic reactions. Here, metal catalyzed cross-coupling reactions 2,3 have been very successful during the last decades, which were recognized by the Nobel Prize in chemistry 2010 for Akira Suzuki, 4,5 Ei-ichi Negishi,6,7 and Richard Heck 8 for their achievements in this field.…”
