One-pot synthesis of CpRe(CO)2H2 and trans-CpRe(CO)2(SnPh3)2 from cis- and trans-CpRe(CO)2Br2 and Ph3SnH. Involvement of a radical-chain sequence in the formation of CpRe(CO)2H2

Inorganica Chimica Acta, 1995
Abstract Treatment of cis- or trans-CpRe(CO)2Br2 (1) with Ph3SnH yields the corresponding dihydride CpRe(CO)2H2 (2) and Ph3SnBr. Conducting the same reaction in the presence of pyridine or Et3N gives trans-CpRe(CO)2(SnPh3)2 (3). The molecular structure of 3 has been determined by X-ray crystallography.

ChemInform Abstract: CHARACTERIZATION AND EVIDENCE FOR ALKYLATION OF HYDRIDODICARBONYLCYCLOPENTADIENYLRHENATE(1‐) ION (CPRE(CO)2H‐) IN THE CONVERSION OF DIHYDRODICARBONYLCYCLOPENTADIENYLRHENIUM (CPRE(CO)2H2) TO CPRE(CO)2R2. SYNTHESIS OF A RHENACYCLOPENTANE AND ITS THERMOLYSIS TO METHYLCYCLOPROPANE

Chemischer Informationsdienst, 1984
AbstractBei dem Versuch, das Dianion von (I) durch Einwirkung von Basen darzustellen, erhielt man den Komplex (II) als K‐Salz (Nachweis durch IR‐ und 1H‐NMR‐Daten), der durch Alkylierung, Deprotonierung und erneute Alkylierung zu dem Produkt (IV) reagiert.
