Efficient hydro-deoxygenation of lignin derived phenolic compounds over bifunctional catalysts with optimized acid/metal interactions

Efficient hydro-deoxygenation (HDO) of lignin derived phenolic compounds was a challenging task due to the incompatibility of the phenolic feedstock and the current hydro-processing catalysts. In this paper, hydro-deoxygenation of lignin derived phenolic compounds over a series of bifunctional catalysts with different metal/acid interactions was firstly carried out. It was found that the distance between the acidic site and noble metal played an important role in the catalytic performance of phenolic hydro-deoxygenation. A highly stable bifunctional catalyst for hydro-deoxygenation of lignin derived phenolic compounds was obtained through simple selective deposition of Pt on alumina in a commonly used Al2O3-ZSM-5 nanocomposite. The bifunctional catalyst retained its complete deoxygenation capacity for more than 500 h. The catalyst can also be used for the HDO of various phenolic model compounds and real bio-oil derived from lignin. A correction of the generally accepted the closer the better criterion in metal/acid bifunctional catalysts when used in bio-oxygenate HDO was also discussed.

Behavior of allylamines in the system KOH-DMSO

Isomerization of triallylamine in the system KOH-DMSO at 90-100°C leads to formation of tris(1-propenyl)amine in quantitative yield. Under similar conditions, diallyl(ethyl)amine is converted into ethylbis(1-propenyl)amine and 1-ethyl-3-methylcyclohexane. Diallylamine in KOH-DMSO gives rise to a complex mixture of products consisting of bis(1-propenyl)amine, methylbis(1-propenyl) amine, 1-ethyl-3-methylcyclohexane, and 2-ethyl-3,5-dimethylpiperidine. Ways of formation of these products are discussed.

Organolanthanide catalyzed hydrogenation and hydrosilylation of substituted methylenecycloalkanes

This communication presents a study of the scope of the catalytic hydrogenation and hydrosilylation of chiral exomethylene-substituted cyclopentanes and cyclohexanes utilizing the organolanthanide precatalysts Cp2* LnCH(SiMe3)2 (Cp* = C5Me5; Ln = Sm, Yb). Both reaction types are sterically driven and lead to the cis-diastereomer as the major product. Additionally, the hydrosilylation is regiospecific, the silane being placed exclusively at the terminal position of the double bond.
