Transition Metal Complexes with PhAsH2 and Ph2As2H2 Ligands; Structure and Epimerisation of meso-Ph2As2H2[Mn(CO)2C5H5]2Phenylarsine, PhAsH2, reacts with the tetrahydrofuran adducts (CO)5M(THF) (M = Cr, Mo, W) to give the corresponding pentacarbonylmetal complexes (CO)5MAsH2Ph (1-3) in good yields. Reaction of C5H5(CO)2Mn(THF)with PhAsH2, however, leads to a product mixture from which the binuclear dipheyldiarsane derivative C5H5(CO)2Mn(PhHAs-AsHPh)Mn(CO)2C5H5 (4) has been isolated. X-ray structure analysis and epimerisation reaction of the complex-stabilized diphenyldiarsane are described.
Notes:
Phenylarsin, PhAsH2, läßt sich mit den Tetrahydrofuran-Addukten (CO)5M(THF) (M = Cr, Mo, W)in guten Ausbeuten zu den entsprechenden Pentacarbonylmetall-Derivaten (CO)5MAsH2Ph (1-3) umsetzen. Die Reaktion von C5H5(CO)2Mn(THF) mit, PhAsH2 führt dagegen zu einem Gemisch von Produkten, aus dem der zweikernige Diphenyldirasan-Komplex C5H5(CO)2Mn-(PhHAs-AsHPh)Mn(CO)2C5H5 (4) isoliert wird. Röntgenstrukturanalyse und Epimerisierungsreaktionen des komplex-stabilisierten Diphenyldiarsans werden beschrieben.
