Alkyltechnetium Oxides: First Examples and Reactions

Abstract

A “diagonal relationship” between technetium(VII) and osmium(VIII) can be proposed based on the properties of the newly synthesized title compounds. Like the valence‐isoelectronic OsO 4 , MeTcO 3 adds olefins to form metallacycles (→ cis ‐diols), whereas the formally analogous MeReO 3 epoxidates olefins in the presence of H 2 O 2 . This difference is presumably due to the oxidizing strength of Tc VII being much greater than that of Re VII .
