In this article, we report on the development of new metal-based anticancer agents with imaging, chemotherapeutic and photosensitizing properties. Hence, a new heterobimetallic complex (Pt-LQ-Re) was prepared by connecting a non-conventional trans-chlorido Pt(ii) complex to a photoactive Re tricarbonyl unit (LQ-Re), which can be replaced by 99mTc to allow for in vivo imaging. We describe the ph...
Cyclopentadienylmolybdenum(II) tricarbonyl dimer exists in two different equilibrium conformations: trans and gauche. Ultrafast photoexcitation in the ultraviolet cleaves the Mo-Mo bond, permitting observation of the subsequent geminate rebinding reaction (t(rebinding) = 31.6 ps) by monitoring infrared bleach recoveries at frequencies corresponding to the CO stretches of the trans and gauche is...
Thionitrosyl Complexes, Nit rosy 1 Chromium Complexes A nitromethane solution of NS+PFe-, obtained in situ from N3S3CI3 and AgPF6 (1:3), reacts with benzene tricarbonyl chromium in acetonitrile solution to give the thionitrosylcontaining salt [Cr(NS)(NC-Me)s](PF6)2 (1)In the presence of Zerf-butyl isocyanide and Zn powder, 1 is reduced to [Cr(NS)(CN-CMe3)s]PF6 (3), while subsequent oxidation of...
Tetronic acids, 4-hydroxy-5H-furan-2-ones, constitute a class of heterocyclic compounds with potent biological and pharmacological activity. The beta, beta'-tricarbonyl moiety plays an integral role in biological systems and forms a variety of metal complexes. In this report, we present the complexation reactions of 3-ethoxycarbonyl tetronic acids with acetates and chlorides of Cu(II) and Co(II...
