Phosphine-alkene ligand-mediated alkyl-alkyl and alkyl-halide elimination processes from palladium(II).
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.
متن کاملLanthanide-mediated phosphoester hydrolysis and phosphate elimination from phosphopeptides.
Lanthanide ions can mediate both phosphomonoester hydrolysis and beta-elimination of inorganic phosphate from polypeptide substrates under near-physiological conditions of pH, temperature, and salt.
متن کاملPrevention of antibody-mediated elimination of ligand-targeted liposomes by using poly(ethylene glycol)-modified lipids.
One of the major obstacles in the development of ligand-targeted liposomes is poor liposome circulation longevity as a result of antibody-mediated elimination of these highly immunogenic carriers. Because studies from our laboratory suggest that it is not possible to reduce the immunogenicity of ligand-conjugated liposomes by using surface-grafted poly(ethylene glycol) (PEG), we investigated th...
متن کاملRoaming‐Mediated CH2NH Elimination from the Ionization of Aromatic Ethylamines
The ionization of aromatic ethylamines by photons or electrons leads to elimination of CH2NH fragments, supposedly deriving from the McLafferty rearrangement involving intramolecular γ-hydrogen transfer. Using tryptamine and phenethylamine as examples, the results reported here suggest that the McLafferty mechanism is inadequate for interpreting the observations of CH2NH elimination due to much...
متن کاملCD4+ T cells can protect APC from CTL-mediated elimination.
Professional APC play a central role in generating antiviral CD8(+) CTL immunity. However, the fate of such APC following interaction with these same CTL remains poorly understood. We have shown previously that prolonged Ag presentation persists in the presence of a strong CTL response following HSV infection. In this study, we examined the mechanism of survival of APC in vivo when presenting a...
