We report herein a new family of carbene ligands based on an indolizine-ylidene (Indolizy) moiety. The corresponding gold(I) complexes are easily obtained from the gold(I)-promoted cyclization allenylpyridine precursors. Evaluation electronic properties by experimental methods and also DFT calculations confirms strong σ-donating π-accepting these ligands. Cationization generates catalytic speci...

A method for asymmetric alkyl-alkyl Suzuki reactions of unactivated secondary alkyl electrophiles, specifically, cross-couplings of racemic acylated halohydrins with alkylborane reagents, has been developed. A range of protected bromohydrins, as well as a protected chlorohydrin and a homologated bromohydrin, are coupled in good ee by a catalyst derived from commercially available components.

N-Diphenylphosphino-7-aza-benzobicyclo[2.2.1]hept-2-ene (2) behaves as a chelating phosphine-alkene ligand for Pd(0) and Pd(II), promoting direct alkyl-alkyl and indirect alkyl-halide reductive elimination reactions due to the stabilisation of the resulting bis(phosphine-alkene)Pd(0) complex.

Polymer nanoparticles (PNPs) were formed from amphiphilic diblock copolymers consisting of a hydrophilic block with pendant polyethylene glycol tosylate (PEG-OTs) groups and a hydrophobic block with pendant terthiophene (TTT) groups. The resulting PNPs were characterized using dynamic light scattering (DLS) and transmission electron microscopy (TEM) to determine size, shape, and polydispersity....

The 2,3,4-tri-toluenesulfonate ester derivatives of the methyl pyranosides of l-arabinose, d-ribose, d-lyxose, and d-xylose have been prepared, and their substitution reactions with various nucleophiles have been examined. For arabinose, xylose, and ribose, highly regioselective monosubstitutions were observed with benzoate, nitrite, and azide anions. These reactions have led to short and simpl...

Vesicles formed from the cationic surfactant, cetyltrimethylammonium tosylate (CTAT) and the anionic surfactant, sodium dodecylbenzenesulfonate (SDBS), were used to sequester the anionic dye carboxyfluorescein. Carboxyfluorescein was efficiently sequestered in CTAT-rich vesicles via two mechanisms: encapsulation in the inner water pool and electrostatic adsorption to the charged bilayer. The ap...
