A very straightforward one-pot method has been developed for preparation of air-stable CpPd(NHC)Cl complexes 1a-d. This new class of well-defined NHC-Pd complexes exhibits high catalytic activity in Kumada-Tamao-Corriu cross-coupling reaction involving various aryl and heteroaryl chlorides. Notably, the less sterically encumbered NHC ligand around Pd centre showed higher catalytic activity.

The PdCl2-promoted reactions of methylenecyclopropanes (MCPs) 1 bearing diaryl substituents on the terminal double bond were carefully investigated. The solvents employed significantly affected the reaction outcomes. It was found that dimeric allylpalladium(ii) complexes 2a-2f can be obtained as the sole products in acceptable to good yields under mild reaction conditions with THF as the solvent, while dimeric allylpalladium(ii) complexes 2a-2f along with another type of dimeric allylpalladium(ii) complexes 4a-4e can be obtained in good to high total yields if N,N-dimethylacetamide (DMAc) was used as the solvent. Moreover, using N,N-dimethylformamide (DMF) as the solvent in the presence of water, it was found that water can also participate in the reaction to form another type of dimeric allylpalladium(ii) complex 6 as the minor product. All of these dimeric allylpalladium(ii) complexes reported in the paper have been characterized by X-ray crystal structure diffraction.

A series of designed palladium biscarbene complexes including saturated and unsaturated N-heterocyclic carbene (NHC) moieties have been prepared by the carbene transfer methods. All of these complexes have been characterized by 1H and 13C NMR spectroscopy as well as X-ray diffraction analysis. The reactivity of Pd-C(saturated NHC) is distinct from that of Pd-C(unsaturated NHC). The Pd-C(saturated NHC) bonds are fairly stable toward reagents such as CF3COOH, AgBF4 and I2, whereas Pd-C(unsaturated NHC) bonds are readily cleaved under the similar conditions. Notably, the catalytically activity of these palladium complexes on Suzuki-Miyaura coupling follows the order: (sat-NHC)2PdCl2 > (sat-NHC)(unsat-NHC)PdCl2 > (unsat-NHC)2PdCl2.

We have studied the ion pair structure of [NHC-Au(eta2-3- hexyne)][BF4] (NHC = nitrogen-heterocyclic carbene) by solution NOE NMR spectroscopy and relativistic DFT calculation. The neutral complexes [NHC-AuCl] have been synthesized through an improved, silver-free one-pot synthesis, by reaction (in air and using solvents and substrates without any previous purification) of the appropriate [NHC(H)]Cl, gold precursor, and KHCO3. Ion pairs were generated in situ in NMR tubes. In our previous work, two main ion pair orientations were observed for unsaturated NHC ligands: one with the anion close to the carbene backbone (A, most populated) and another with the anion close to the alkyne (B). Here we focus on the effect of the carbene backbone on the ion pair structure, comparing the unsaturated NHC (1BF4) with two different variants: a saturated NHC (2BF4) and a polycyclic ligand with an extended aromatic system (3BF4). For 2BF4, the A:B ratio remains almost the same as for 1BF4, while the ion pair structure of 3BF4 becomes mainly nonspecific, with a slight preference for the orientation B. Both cases can be explained analyzing the DFT Coulomb potential map, which shows an attractive region on the backbone of 2BF4 and a flat weak potential around the whole 3BF 4.

Eight imidazolium-based salts with the weakly-coordinating anions [BArF]? and [Al(OtC4F9)4]? ([BArF]? = tetrakis{3,5-bis(trifluoromethyl)phenyl}borate) have been synthesized. Characterization by 1H NMR spectroscopy shows that the salts are fully dissociated in solution. Six examples have been further characterized by X-ray crystallography, revealing that weak hydrogen bonds do occur in the solid phase between the imidazolium cations and weakly coordinating anions. Comparison with the bulky [IDiPPH] imidazolium cation (IDiPPH = 1,3-bis{2,6-bis(diisopropyl)phenyl}imidazolium) shows that large steric bulk close to the imidazolium protons can preclude hydrogen bonds from forming. Differential scanning calorimetry of the salts reveal that all are thermally stable up to 200 C which renders them as potentially suitable background electrolytes for electrochemical processes which take place at elevated temperatures.

A series of gold(i) N-heterocyclic carbene complexes containing monoanionic acylchalcogenourea (chalcogen = S, Se) ligands was prepared and characterised by various spectroscopic methods and X-ray diffraction. The compounds were conveniently accessible in good yields through a one-pot reaction involving [AuCl(tht)] (tht = tetrahydrothiophene), the imidazolium salt and the acylchalcogenourea in the presence of excess base. The X-ray diffraction experiments showed that in these complexes, the normally chelating ligands adopt the rare kappaS/Se-coordination mode in which only the chalcogen is bound to gold.

Platinum N-heterocyclic carbene (NHC) complexes have been synthesized and used as precatalysts in the reductive cyclization of diynes and eynes. 2,5-Dihydrofurans, -pyrroles, and -cyclopentenes were obtained as reductive cyclization products from oxygen-, nitrogen-, and carbon-tethered substrates, respectively. The yield and product of the reaction were highly dependent upon the substrate and the substituent on the alkyne.

The use of microwave heating for the synthesis of a series of (N-heterocyclic carbene)Ni(Cp)Cl complexes is presented. This protocol allows for a considerable reduction of the reaction times required using conventional heating, while affording comparable or better yields of the desired complexes. Their application as pre-catalysts in the microwave-assisted anaerobic oxidation of secondary alcohols is also discussed.
