The mononuclear silver(I) complex [AgL(HL)· DMF] (I) (HL = C 6H13O2N2Br) has been prepared and characterized by physicochemical and spectroscopic methods, single crystal X-ray diffraction, cyclic voltammetry, and antibacterial activity tests. The complex crystallized in the triclinic system, and each Ag(I) is six-coordinate with a distorted octahedral geometry. The ligands chelate the metal center with N, O, and Br atoms from two different Schiff base ligands. O- H···O intermolecular hydrogen bonds connect adjacent complex molecules to form zigzag one-dimensional linear chains along the b axis. Cyclic voltammetry showed that the complex displays an irreversible reduction process at -0.41 V. The data from antibacterial activity tests indicate that the complex inhibits the growth of Staphyloccus aureus and Bacillus subtilis Cohn. Springer Science+Business Media B.V. 2010.

A chiral carbene-catalyzed [3+3] annulation of α-bromoenals with 2-aminobenzimidazoles providing pyrimido[1,2-a]benzimidazoles has been described. This protocol features a broad scope and good functional group tolerance. Biological studies indicated that the formed pyrimido[1,2-a]benzimidazole exhibited moderate cytotoxic activity against tumor cells.

The unprecedented enantioselective NHC-catalyzed [3 + 3] annulation of α-bromoenals with amidines via a dual C-N bond formation is described. The protocol allows a rapid preparation of 5,6-dihydropyrimidinones in acceptable yields with good enantioselectivities.
