Exploring the nitrosyl-approach: "Re(CO2NO)"- and "Tc(CO)(2)(NO)"-complexes provide new pathways for bioorganometallic chemistry

Nitrosylation reactions are rare in the context of low valent Re(l)- and Tc(l)-tricarbonyl complexes so far. We herein de:scribe a method for the conversion of a "M(CO)(3)-Moiety" (M = Re, Tc) into a dicarbonyl-nitrosyl Moiety "M(CO)(2)NO", the synthesis of important precursor complexes and intermediates and possible applications for this new kind of Re- and Tc-chemistry.status: publishe
