Hydrogenation of alkenes containing polarized C=C double bonds has been achieved with iron-based homogeneous catalysts bearing a bis(phosphino)amine pincer ligand. Under standard catalytic conditions (5 mol % of (PNHPiPr)Fe(H)(2)(CO) (PNHPiPr = NH(CH(2)CH(2)PiPr(2))(2)), 23 degrees...
The sequenced Diels–Alder/oxidation reaction represents a powerful route for the construction of aromatic compounds in organic synthesis. The oxidative Diels–Alder reaction with H2 evolution would be a more ideal approach that can avoid the additional oxidation procedure and stoichiometric oxidant. Herei...
demonstrated to significantly enhance mass transfer characteristic of gas molecules due to the large interfacial area, special circulation flow field and the short path required for molecular diffusion across the liquid film40,41,42,43. In addition, Taylor flow is characterized for its uniformity, mak...
The content of carbon and hydrogen in the bio-oil is increased due to the hydrogenation reaction which also reduces the nitrogen and oxygen content of the products. An increase in the bio-oil heating value (up to 39 MJ/kg) is also observed using this process. The catalyst promotes ...
