The [Pd(SIPr)(PCy3)] complex efficiently promotes a tandem process involving dehydrogenation of formic acid and hydrogenation of C-C multiple bonds using H2 formed in situ. The isolation of a key catalytic hydridoformatopalladium species, [Pd{OC(O)H}(H)(IPr)(PCy3)], is reported. The complex plays a key role in the Pd(0)-mediated formation of hydrogen from(More)
N-Heterocyclic carbenes do it again! [Pd(SIPr)(PCy(3))] (1; SIPr=N,N'-(bis(2,6-diisopropylphenyl)imidazolidine), which is stable under H(2), was shown to be a highly active catalyst for the hydrogenation of a wide range of alkenes and alkynes. Reactions proceed under mild conditions (relatively low Pd loading, RT, low pressures of H(2)) even when sterically(More)
A series of [Pd(NHC)(PR(3))] complexes quantitatively form [Pd(η(2)-O(2))(NHC)(PR(3))] products when submitted to an dioxygen atmosphere. Synthetic details and structural features of these Pd-peroxo complexes are described. The palladium compounds were found to be efficient catalysts in the oxidation of alcohols into corresponding carbonyl compounds using(More)
The first synthesis of α-(trifluoromethyl)-β-lactam ((S)-1) is reported. The route starts from α-(trifluoromethyl)acrylic acid (2). Conjugate addition of α-(p-methoxyphenyl)ethylamine ((S)-3b), generated an addition adduct 4b which was cyclised to β-lactam 5b. Separation of the diastereoisomers by chromatography gave ((αS,3S)-5b). N-Debenzylation afforded(More)
An even split: In sharp contrast with the general behavior of Pd(0) complexes, [Pd(IPr)(PCy(3))] is able to activate the H-H bond. The resulting trans-[Pd(H)(2)(IPr)(PCy(3))] is the first isolated mononuclear dihydride palladium compound. Its formation is supported by multinuclear NMR spectroscopy, density functional calculations, and X-ray diffraction(More)
