Bioactive Heterocycles

The use of the coinage metals copper, silver, and gold enables an efficient and stereo-selective assembly of bioactive heterocycles via allenic intermediates. The synthesis of functionalized allenes by SN2'-substitution or SN2'-reduction is mediated or catalyzed by copper, whereas silver and gold are the catalysts of choice for subsequent 5- or 6-endo-cyclizations. Overall, this sequence proceeds with efficient center-to-axis-to-center chirality transfer.

The tris(pyrazolyl)borate [HB(3,5-(CF3)2Pz)3]− prepared using highly fluorinated 3,5-bis(trifluoromethyl)pyrazole and BH4− is an excellent supporting ligand for the stabilization of a number of rare organometallic complexes of coinage metals. For example, it has enabled the isolation of Cu(I), Ag(I), and Au(I) complexes of CO and ethylene as crystalline solids. Syntheses, spectroscopic and structural features, and properties of [HB(3,5-(CF3)2Pz)3]ML (M = Cu, Ag, Au; L = CO, C2H4) are the main focus of this discussion. Several metal adducts based on the tris(triazolyl)borate [HB(3,5-(CF3)2Tz)3]− supporting ligand as well as the cationic, coinage metal multi-alkene complexes containing the [SbF6]− counterion are also discussed.

Weak Intermolecular Forces

The complexation of coinage metal cations with [2.2.2]paracyclophane and deltaphane has been investigated by means of density functional theory (DFT) calculations employing the PBE0-D3 hybrid functional, which incorporates explicit dispersion corrections to account for the weak intermolecular forces that are important in the systems studied. Natural bond orbital (NBO) analyses, Bader's Atoms in Molecules theory analyses as well as localised molecular orbital – energy decomposition analyses (LMO-EDAs) have been carried out to further investigate the electronic structure and bonding of the complexes. It was found that both cyclophanes bind strongest with gold ions, followed closely by copper ions and lastly silver ions. The two fragments interact in a non-covalent fashion in these complexes and the metal preferentially resides at the periphery of the molecular cavity of the cyclophane.
