Aqueous One-Pot Synthesis of Derivatized Cyclopentadienyl-Tricarbonyl Complexes of99mTc with an In Situ CO Source: Application to a Serotonergic Receptor Ligand
Instant radiopharmaceuticals-just add [(99m) TcO4 ](-) in water! Half-sandwich complexes of the type [(RCOCp)(99m) Tc(CO)3 ] (e.g. 1) were synthesized in a single step in water from [(99m) TcO4 ](-) . The acidification of the Cp ring by a carbonyl substituent and the use of K2 [H3 BCO2 ] as a reducing agent and in situ source of CO are instrumental in the synthesis.

llium (3) in nearly quantitative yield. Reactions of 3 with Mn(CO)5Br, Re(CO)5Br, [Rh(CO)2Cl]2 or FeCl2 lead to the respective η5-benzoylcyclopentadienyl derivatives of these metals, and demonstrate the utility of 3 in organometallic syntheses. Reactions of several of these organometallic ketones with cymantrenyllithium [(η5-C5H4Li)Mn(CO)3] provide a useful new route to bimetallic compounds.
