Abstract

Multiple Bonds between Main Group Elements and Transition Metals, XC. – Selective Formation of Alkylrhenium Oxides from Glycolato Complexes Alkylrhenium(VII) and alkylrhenium(VI) oxides, previously not known or hardly accessible, are selectively synthesized from glycolato(O,O') complexes. These are formed in easy terms from methyltrioxorhenium(VII) and aliphatic vic‐diols, e.g. glycol and pinacol, by both redoxneutral and reductive condensation reactions (ReVII → ReVI), respectively. The dinuclear glycolato complex 3 exhibits a centrosymmetric molecular structure with an octahedral core geometry around the metal atom. The mononuclear Re(VII) compound 2 forms a distorted trigonal bipyramidal structure (single crystal X‐ray diffraction).
