Darstellung von 2‐Aryl‐(4‐R)‐arseninen durch Arsacyclohexadienol → Arsabenzol‐Umlagerung

Abstract: Durch KOH/[18]Krone‐6 phasentransfer‐katalysierte Addition von Arylarsanen (Phenylarsan, p‐Tolylarsan) an (3‐R)‐3‐Methoxy‐1,4‐pentadiine 13 werden cis/trans‐isomere 1‐Aryl‐1,4‐dihydro‐(4‐R)‐4‐methoxyarsenine 14 und 15 erhalten, deren 1H‐NMR‐ und 13C‐NMR‐Spektren diskutiert werden. ‐ Die 1,4‐Dihydroarsenine 14 und 15 lagern sich bei Umsetzung mit BF3‐Etherat oder p‐Toluolsulfonsäure unter 1,2‐Arylverschiebung in die 2‐Aryl‐(4‐R)‐arsenine 22 bzw. 24 um. Diese Umlagerung stellt das erste elementorganische Analogo… Show more

“…[1][2] Although less well studied than their all-carbon analogues, a variety of heteroarene complexes of the Group 6 M(CO) 3 series are also known. Pyridines, typically η 1 donor ligands, can be coerced into η 6 coordination by use of bulky substituents in the 2 and 6 positions, [3][4] while halfsandwich complexes of η 6 phosphabenzene, [5][6][7] arsabenzene, [8][9] and stibabenzene 9 ligands have also been reported. Silabenzenes 10 and germabenzenes, 11 kinetically stabilised by large substituents, have also been coordinated to group 6 tricarbonyl fragments.…”
