Utilising Sodium-Mediated Ferration for Regioselective Functionalisation of Fluoroarenes via C?H and C?F Bond Activations

Pairing iron bis(amide) Fe(HMDS)2 with Na(HMDS) to form new sodium ferrate base [(dioxane)0.5?NaFe(HMDS)3] (1) enables regioselective mono and di-ferration (via direct Fe?H exchange) of a wide range of fluoroaromatic substrates under mild reaction conditions. Trapping of several ferrated intermediates has provided key insight into how synchronised Na/Fe cooperation operates in these transformations. Furthermore, using excess 1 at 80 °C switches on a remarkable cascade process inducing the collective twofold C?H/threefold C?F bond activations, where each C?H bond is transformed to a C?Fe bond whereas each C?F bond is transformed into a C?N bond.

A simple base-mediated halogenation of acidic sp2 C-H bonds under noncryogenic conditions

(Chemical Equation Presented) A new method has been developed for in situ halogenation of acidic sp2 carbon-hydrogen bonds in heterocycles and electron-deficient arenes. Either selective monohalogenation or one-step exhaustive polyhalogenation is possible for substrates possessing several C-H bonds that are flanked by electron-withdrawing groups. For the most acidic arenes, such as pentafluorobenzene, K3PO4 base can be employed instead of BuLi for metalation/halogenation sequences.

Halogenation reactions

A method of halogenating an aromatic compound which comprises the steps of reacting an halogenating agent with the aromatic compound in the presence of fluorine and an acid, wherein the halogenating agent is at least one of an iodinating agent, a brominating agent and an chlorinating agent.

Elemental fluorine. Part 4. Use of elemental fluorine for the halogenation of aromatics

New methodolgy for direct iodination of benzenoid compounds has been developed; the aromatic substrate is simply mixed with iodine and sulfuric acid, suspended in an inert medium, such as 1,1,2-trichlorotrifluoroethane (CF2ClCFCl2) or perfluorocarbon, and elemental fluorine is passed through the system at room temperature. High conversions to iodoaromatic products occur, even with some deactivated systems, e.g. nitrobenzene. A very powerful brominating system is produced using the analagous methodology.

C-I STRETCHING VIBRATIONS IN IODOBENZENES

Comparison of the calculated and experimental IR and Raman spectra of a series of iodobenzenes showed that the C-I stretching vibrations for these compounds correspond to a very highly polarized Raman band 150 - 270 cm-1 (ρ = 0.1).The position of this band depends on the mass of the para substituent and relative position of the fluorine and iodine atoms in the molecule.The UV absorption spectral data indicate an interaction of the iodine atom and para substituents through the ?-system.Opposite substituent effects on the change in intensity of the B-band in the UV spectra of iodobenzenes and tetrafluoroiodobenzenes were noted.
