2008_14/2008Reactions of Pendant Boryl Groups in Cp–Metal Complexes: Heterocyclic Ring Annelation in a CpIr System (Eur. J. Inorg. Chem. 14/2008)

The cover picture shows the regioselective hydroboration of (trans-CH3–CH=CH–C5H4)Ir(cod) (X-ray structure on the left) with bis(pentafluorophenyl)borane followed by an intermolecular electrophilic aromatic substitution reaction at the Cp ring to yield the respective boron-containing heterocycle. In this case the iridium metal acts as an internal metal base to yield the corresponding zwitterionic iridium hydride complex (X-ray structure on the right). At the bottom, the 1H NMR (600 MHz, CD2Cl2, –20 °C) spectrum of the iridium hydride complex is pictured with the omission of the Ir-1H domain at δ = –12.23 ppm. The corresponding 19F NMR (564 MHz, CD2Cl2, –30 °C) spectrum with expanded areas is depicted in the background. Further details are provided in the article by G. Erker et al. on p. 2273ff.
