Due to the specific physical and chemical properties of perfluorinated chains, i.e. stiffness, increased size and extreme hydrophobicity/lipophobicity, fluorosurfactants exhibit enhanced surfactant properties. Consequently, fluorosurfactants have found wide applications in consumer products, industries and research laboratories. In this article, the use of fluorosurfactants for applications in catalytic processes is reviewed. The role and benefits of such additives in catalytic processes to favor the formation of micellar systems in water, in supercritical CO2 or in reactions taking place at liquid-liquid interfaces by favoring the formation of emulsions or by stabilizing microdroplets, will be discussed. Finally, an interesting example of catalysis which takes place at the air-water interface thanks to a fluorous catalytic Langmuir film, will be highlighted.

A straightforward methodology for the synthesis of libraries of chiral tris-ligated cationic platinum complexes and their in situ evaluation as asymmetric carbophilic catalysts in a model domino hydroarylation/cyclization reaction of a 1,6-enyne was developed. A catalyst-generation process based on a combination of a monodentate and a bidentate phosphorus ligand allowed the formation of 108 chiral complexes. One-pot screening of the stereoinduction obtained with this library in a test domino addition/cyclization reaction validated this approach and stressed the key role played by the monodentate ligand partner in obtaining high enantioselectivities. In the case of two challenging substrate/nucleophile combinations, the combinatorial approach resulted in a significant gain in enantioselectivity.

Chelation kinetics of the complexes Ru(CO)4(eta1-(P-P)) have been studied in heptane, where P-P = Ph2P(CH2)nPPh2 (n = 1, 2, 3, or 4, i.e., dppm, dppe, dppp, or dppb), Ph2P(NMe)PPh2 (dppma), Ph2P(o-C6H4)PPh2 (dpp-benzene), or R2P(CH2)2PR2 (R = Me or Cy, i.e., dmpe or dcpe). The complexes were prepared in situ by reaction of the bidentate ligands with Ru(CO)4(C2H4), which itself was prepared in situ by photolysis of Ru3(CO)12 under C2H4. The initially formed Ru(CO)4(eta1-(P-P)) complexes react cleanly to form axial-equatorial Ru(CO)3(eta2-(P-P)), as shown by the crystallographic structures of the products when P-P = dppe, dmpe, and dpp-benzene and the close similarity of their FTIR spectra to those of the other products. The chelated products undergo further reaction in solution or the solid state, and the product when P-P = dppma has been characterized by crystallography as Ru2-(CO)3(mu-PPh2)(mu-Ph2PNMePPh2). The kinetics of the displacement of CO from Ru(CO)4(eta1-(P-P)) in n-heptane are characterized by DeltaH? values that are lower by up to 9 kcal mol-1 than those of their monodentate P-donor analogues. DeltaS? values range from quite positive to slightly negative and suggest a trend from purely dissociative to appreciably associative mechanisms along the series P-P = dpp-benzene < dcpe < dmpe < dppp ? dppm ? dppbu ? dppe ? dppma. This contrasts with the CO-dissociative reactions of analogous Ru(CO)4L complexes when L = monodentate P-donor ligands.

Cu(iii)-CF3 complexes are important intermediates of both synthetic and mechanistic interest. This study describes the isolation, and spectroscopic and X-ray crystallographic characterization of CuIII-CF3 complexes 2-4 with typical monophosphine ligands PPh3 and Buchwald-type biarylmonophosphines. Distinct from the ion-pair [P2Cu(i)]+[Cu(iii)(CF3)4]? structures of 2 and 4 (P: PPh3 or SPhos), complex 3 exhibits a novel OH-bridged Ag(i)-Cu(iii) dinuclear structure with XPhos-coordinated linear Ag(i) and square planar Cu(iii) components. This is the first heterobimetallic Cu(iii)-CF3 complex confirmed by both solution-phase NMR spectroscopy and solid state X-ray crystal structure analysis. Complex 3 is found to have the LUMO orbital of major sigma*(Cu-CF3) nature and electrophilic CF3 ligands. Accordingly, complex 3 is able to trifluoromethylate 2 equivalents of aryl boronic acids in up to quantitative yields, regardless of the inert or oxidative conditions. In contrast, the ion-pair complexes 2 and 4 show low reactivity. This study enriches the coordination and reactivity chemistry of Cu(iii)-CF3 compounds and shows the feasibility of modulation of structures and reactivity by ligand design, which may inspire future efforts on Cu(iii)-CF3 chemistry.

The incredible bulk: The first palladium-catalyzed amidation of five-membered heterocyclic bromides with multiple heteroatoms was achieved using the Pd/1 catalyst system. N-Arylated imidazoles, pyrazoles, thiazoles, pyrroles, and thiophenes were synthesized in moderate to excellent yield. Experimental results and DFT calculations point to the need for an electron-rich and sterically demanding biaryl phosphine ligand to promote these difficult reactions. Copyright

A series of N-heterocyclic carbene (NHC)/PR3 palladium(ii) and palladium(0) complexes has been synthesized and fully characterized. X-ray crystallographic data have allowed comparison of ligand steric properties. The NHC ligand was found to vary its steric properties as a function of the phosphine co-ligand. These complexes display interesting catalytic properties in the Suzuki-Miyaura reaction performed in aqueous media. The pre-catalyst [PdCl2(IPr)(XPhos)] (IPr = N,N?-bis-(2,6-diisopropylphenyl) imidazol-2-ylidene; XPhos = 2-dicyclohexylphosphino-2?,4?,6?- triisopropylbiphenyl) was found to be the most efficient system, promoting the coupling of a wide range of aryl chlorides with boronic acids in aqueous media with a typical catalyst loading of 0.03 mol%.
