Reaction of three cyclic thioester ligands with triiron dodecacarbonyl and possible reaction mechanisms

Abstract : Three cyclic thioesters of the formula “-SCH2CH2SCO(CH2)n-” (L1, n = 0 ? L2, = 1 , L3, n = 2) and their reactions with Fe 3(CO) 12 are reported. All the reactions produced a known diiron complex, [Fe 2(μ - S 2C 2H 4) (CO) 6] (1), which suggested that in the reactions, cleavage of C-S bond to generate “SCH 2CH 2S ” fragment is a common pathway for all the three ligands. In the case of ligand L2, a new complex 2, [Fe 2{ μ - SC 2H 4(SCH 2) - κ } (CO) 6] was isolated and structurally characterized. In the reaction of ligand L3, an unknown iron carbonyl product was isolated in addition to complex 1. Although its precise structure was not established due to its instability and low yield, its infrared spectrum and decomposing into complex 1 implied that the product may be a cluster with higher nuclearity. The experimental observations suggested that with the increase of the ring size of the cyclic thioester ligands, further bond cleavages were involved in the reaction in addition to that leading to complex 1. GRAPHICAL ABSTRACT: SYNOPSIS Reaction of cyclic thioester ligands with triiron dodecacarbonyl leads to scission of C-S (C) bond which is initiated by the coordination of the S atom to the Fe atom. The larger the ring size of the ligand, the more diverse are the bond cleavages. [Figure not available: see fulltext.].

Chealators of type XN1 S1 X1 for radioactive isotopes, their metal complexes and their diagnostic and therapeutical uses

This invention relates to new bifunctional chelating agents with intermittent chalcogen atoms, pharmaceuticals containing these compounds, their use in radiodiagnostics and radiotherapy, and methods for the production of these compounds. The compound according to the invention has the general formula (I) where M represents a radionuclide and L a ligand of the general formula (II). It was found, surprisingly, that these new, bifunctional chelating agents with intermittent chalcogen atoms and their coupling products with compounds that accumulate specifically are excellently suited for producing radiopharmaceuticals for diagnostic and therapeutic purposes.
