Catalytic transfer hydrogenation/hydrogenolysis of guaiacol to cyclohexane over bimetallic RuRe/C catalysts

The hydrodeoxygenation of lignin monomer guaiacol via catalytic transfer hydrogenation was studied with 2-propanol as a hydrogen donor and Ru-based catalysts. Guaiacol was mainly converted into a partially deoxygenated product, cyclohexanol (>?70% selectivity), over Ru/C catalysts with the hydrogen produced in-situ from 2-propanol. An addition of Re to Ru/C catalysts significantly enhanced the rate of C—O hydrogenolysis, resulting in the complete deoxygenation to cyclohexane (~?60% selectivity). The remarkable deoxygenation ability of the bimetallic RuRe/C catalyst is attributed to its bifunctional characteristic, by which Ru catalyzes the hydrogenation-hydrogenolysis of guaiacol and Re provides acid sites to promote cyclohexane production via hydrogenolysis.

The present invention relates to novel 3-aminoalkyl-1,3-dihydro-2H-indol-2-one derivatives, to their preparation and to their therapeutic application. The compounds of the present invention correspond to the formula (I): in which the variables are as set forth in the specification. These compounds exhibit a strong affinity and a high selectivity for human arginine-vasopressin (AVP) V1a receptors and some compounds additionally exhibit a strong affinity for AVP V1b receptors.
Isopropoxy as a masked hydroxy group in aryl oxidative coupling reactions
Bushby,Lu
