Picolyl substituted N-heterocyclic carbene/palladium catalyzed Heck reactions
Heck reaction imidazolinium salt palladium
2010/10/18
Novel 1,3-dialkylimidazolinium and 1,3- dialkyltetrahydropyrimidinium hexafluorophosphate salts as N-heterocyclic carbene precursors were prepared by reacting N,N'-dialkylethandiamine or N,N'-dialkylp...
New Alkoxyzinc Salts Mediated Chemoselective Transesterification Reactions
Chemoselective transesterification zinc bromide zinc acetate alkoxyzinc bromide alkoxyzinc acetate
2010/4/19
A new chemoselective method for the transesterification of alkyl esters in the presence of in situ formed alkoxyzinc salts was developed. Electron-rich esters are less reactive than electron poor ones...
Potentiodynamic and potentiostatic polarizations, and a rotating disk electrode technique were used to study the influence of diffusion on the anodic reactions of tungsten (W) in a broad pH range (\si...
