Darstellung und Strukturen von (Et4N)2[Re(CO)3(NCS)3] und (Et4N)[Re(CO)2Br4]

Abstract: Ausgehend von (Et4N)2[Re(CO)3Br3] lassen sich durch einfache Ligandenaustauschreaktionen weitere Rhenium(I)‐ und Rhenium(III)‐Carbonylkomplexe herstellen. In Abwesenheit starker Oxidationsmittel bleibt die faciale Re1(CO)3‐Einheit bei gleichzeitigem Austausch der Bromoliganden erhalten. Mit Trimethylsilylisothiocyanat kann so (Et4N)2[Re(CO)3(NCS)3] in guten Ausbeuten und hoher Reinheit hergestellt werden. Die Verbindung kristallisiert monoklin in der Raumgruppe P21/n, a = 18,442(5), b = 17,724(3), c = 18,668(5… Show more

“…Following a literature procedure, [ReBr 3 (CO) 3 ] 2À 3 is oxidised in a first step with Br 2 to the Re(III) compound [ReBr 4 (CO) 2 ] À 2 in good yield [10]. Compound 2 is unstable in protic solvents and is likely to undergo unexplored disproportion reactions.…”

“…The solvent and excess Br 2 was removed in vacuo and the residue recrystallised from CH 2 Cl 2 /Et 2 O to get 1.4 g of 2 (78% yield) [10]. Compound 2 (500 mg) was dissolved in CH 3 CN and a slight excess (1.5 equiv.)…”
