Lithium Di-‐ and Trimethyl Dimolybdenum(II) Complexes with Mo-‐Mo Quadruple Bonds and Bridging Methyl Groups
(American Chemical Society, 2015)
New dimolybdenum complexes of composition [Mo2{μ-Me}2Li(S)}(μ- X)(μ-N^N)2] (3a−3c), where S = THF or Et2O and N^N represents a bidentate aminopyridinate or amidinate ligand that bridges the quadruply bonded molybdenum ...

β-Hydrogen Elimination Reactions of Nickel and Palladium Methoxides Stabilised by PCP Pincer Ligands
(John Wiley & Sons, 2015)
Nickel and palladium methoxides [((iPr)PCP)M-OMe], which contain the (iPr)PCP pincer ligand, decompose upon heating to give products of different kinds. The palladium derivative cleanly gives the dimeric Pd(0) complex ...

Cell uptake mechanisms of glycosylated cationic pDNA-cyclodextrin nanoparticles
(Royal Society of Chemistry, 2015)
The incorporation of carbohydrate functional elements in the architecture of polycationic amphiphilic cyclodextrins (paCDs) provides glycosylated paCDs (pGaCDs) that form transfectious nanocomplexes (glycoCDplexes) with ...

Conformationally-locked N -glycosides: Exploiting long-range non-glycone interactions in the design of pharmacological chaperones for Gaucher disease
(Elsevier, 2015)
Pyranoid-type glycomimetics having a cis-1,2-fused glucopyranose–2-alkylsulfanyl-1,3-oxazoline (Glc-PSO) structure exhibit an unprecedented specificity as inhibitors of mammalian β-glucosidase. Notably, their inhibitory ...

A Diels–Alder Reaction Triggered by a [4 + 3] Metallacycloaddition
(American Chemical Society, 2015)
The TpMe2Ir(III) complex 1-OH2 (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate), which contains a labile molecule of water and an iridium-bonded alkenyl moiety (−C(R)═C(R)–(R=CO2Me)) as part of a benzo-annulated five-membered ...

Harmonized tuning of nucleic acid and lectin binding properties with multivalent cyclodextrins for macrophage-selective gene delivery
(Royal Society of Chemistry, 2015)
Polycationic amphiphilic cyclodextrins (paCDs) have been shown to behave as efficient non-viral gene carriers paralleling the efficacy of commercial vectors towards a variety of cell lines. Their molecular framework and ...

Synthesis and structure of mixed carboxylate-aminopyridinate and -amidinate complexes of dimolybdenum and ditungsten
(Elsevier, 2015)
We describe in this paper the synthesis and structural characterization of dimolybdenum and ditungsten complexes with MM bonds derived from the metal–metal bonded tetracarboxylates [M2(O2CR)4] and incorporating one or two ...

Rhodium and Iridium Complexes of Bulky Tertiary Phosphine Ligands. Searching for Isolable Cationic M(III) Alkylidenes
(American Chemical Society, 2015)
Cyclometalated chloride complexes of rhodium and iridium based on (5-C5Me5)M(III) fragments that result from the metalation of the xylyl substituent of a coordinated PR2(Xyl) phosphine (Xyl=2,6-Me2C6H3) have been prepared ...

Chiral Rh phosphine–phosphite catalysts immobilized on ionic resins for the enantioselective hydrogenation of olefins in water
(Royal Society of Chemistry, 2015)
The asymmetric hydrogenation of prochiral enamides with Rh complexes bearing chiral phosphine–phosphite ligands (P–OP) supported on sulphonated polystyrene resins has been studied. The complexes have been supported by ...

Glucose conjugation of anti-HIV-1 oligonucleotides containing unmethylated CpG motifs reduces their immunostimulatory activity
(John Wiley & Sons, 2015)
Antisense oligodeoxynucleotides (ODNs) are short synthetic DNA polymers complementary to a target RNA sequence. They are commonly designed to halt a biological event, such as translation or splicing. ODNs are potentially ...
