Scope, limitations and mechanistic aspects in the selective homogeneous palladium-catalyzed reduction of alkenes under transfer hydrogen conditions
Brunel, Jean Michel
, p. 3899 - 3906 (2008/02/03)
A new and efficient mild Pd/P(t-Bu)3 catalyst for selective reduction of various alkenes under transfer hydrogen conditions has been developed leading to the corresponding saturated derivatives in chemical yields varying from 65 to 98%. Mechanistic rationale of this reaction has been also demonstrated.
Bicyclo[2.2.1]heptane-2-methanol Transformations on oxide catalysts
Gasanov,Alieva,Musaev
, p. 272 - 274 (2007/10/03)
Bicyclo[2.2.1]heptane-2-methanol was synthesized by hydrogenation of bicyclo[2.2.1]hept-5-ene-2-methanol in a flow system on fixed-bed oxide catalysts, and its transformations were studied. Dehydration and isomerization of bicycloheptene structure with the double-bond migration were found to be the main transformation routes. Thus, 2-methylenebicyclo[2.2.1]heptane (norcamphene), the product of dehydration, was obtained with 47.2 or 61.0% yield in the presence of γ-Al2O3 or aluminosilicate, respectively. The majority of norcamphene was isomerized to give bi- and monocyclic unsaturated hydrocarbons differing in position of the double bond.
Substituent Effects on 1H Chemical Shifts I-Complete 1H Chemical Shift Assignments of Methyl-Substituted Cyclic Systems
Fisher, Julie,Gradwell, Michael J.
, p. 338 - 346 (2007/10/02)
1H chemical shift assignments are presented for 2-methyladamantane, 2-methylnorbornane (endo and exo) and 2-methylnorbornene (endo and exo).Resonance assignment was achieved using a variety of 1D and 2D homo- and heteronuclear (1H-13C)experiments.The methyl group-induced substituent chemical shift (SCS) is derived and the SCS of protons vicinal to this group is discussed.KEY WORDS Norbornanes Norbornenes Adamantanes 1H NMR Substituent chemical shifts
