A mild method for the regioselective C2-bromination of fused azine N-oxides is presented, employing tosic anhydride as the activator and tetra-n-butylammonium bromide as the nucleophilic bromide source. The C2-brominated compounds are produced in moderate to excellent yields and with excellent regioselectivity in most cases. The potential extension of this method to other halogens, effecting C2-chlorination with Ts2O/TBACl is also presented. Finally, this method could be incorporated into a viable one-pot oxidation/bromination process, using methyltrioxorhenium/urea hydropgen peroxide as the oxidant.

A novel, simple and practical method for the regioselective halogenation of fused heterocyclic N-oxides has been developed. It employs Vilsmeier reagent, generated in situ by POX3and DMF, as both the activating agent and the nucleophilic halide source. The method is amenable across a broad range of substrates, including quinolines, isoquinolines and the diazine N-oxides, possessing a variety of substitution patterns. Furthermore, all of the reagents associated are cheap and easy to obtain. The potential extension of this method to a one-pot oxidation/halogenation sequence that obviates the need for isolation of the N-oxide intermediates is also presented.

We have described herein a series of unsymmetric 1,10-phenanthroline (phen) based aromatic heterocyclic derivatives with triphenylamine (TPA) and thiophene donors (L1-L5) and their respective neutral tricarbonyl rhenium(I) complexes (6a-6e). Comparisons between isomeric compounds L1/L2 and 6a/6b as well as L3/L4/L5 and 6c/6d/6e have been made on their 1H NMR and UV/Vis spectra, single-crystal structures and density function theory (DFT) calculations. The alterations of conjugated system of the whole molecules, originating from the introduction of 2-, 3- or 3,8-substituted TPA and thiophene groups of phen, are responsible for the structural and spectral discrepancy of these structural isomers. In particular, the introduction of TPA and/or thiophene donors at 2-postion of phen (L1 and L3) leads to smaller band gaps than their respective 3-substituted isomers (L2 and L4). In addition, rhenium(I) ion complexation could slightly lower the highest occupied molecular orbital (HOMO) energy levels but significantly decrease the lowest unoccupied molecular orbital (LUMO) energy levels of the molecular system.

Bifunctional Ru(II) complex catalysed carbon-carbon bond formation: an eco-friendly hydrogen borrowing strategy

The atom economical borrowing hydrogen methodology enables the use of alcohols as alkylating agents for selective C-C bond formation. A bifunctional 2-(2-pyridyl-2-ol)-1,10-phenanthroline (phenpy-OH) based Ru(ii) complex (2) was found to be a highly efficient catalyst for the one-pot beta-alkylation of secondary alcohols with primary alcohols and double alkylation of cyclopentanol with different primary alcohols. Exploiting the metal-ligand cooperativity in complex 2, several aromatic, aliphatic and heteroatom substituted alcohols were selectively cross-coupled in high yields using significantly low catalyst loading (0.1 mol%). An outer-sphere mechanism is proposed for this system as exogenous PPh3 has no significant effect on the rate of the reaction. Notably, this is a rare one-pot strategy for beta-alkylation of secondary alcohols using a bifunctional Ru(ii)-complex. Moreover, this atom-economical methodology displayed the highest cumulative turn over frequency (TOF) among all the reported transition metal complexes in cross coupling of alcohols.
