A one-pot, acceptorless dehydrogenative method, using a carbon-supported Pt catalyst (Pt/C) along with KOtBu, has been developed for the synthesis of 2,4,6-trisubstituted pyrimidines from secondary and primary alcohols, amidines. The reaction takes place efficiently wide range substrate scopes (32 examples isolated yields up to 92%). Pt/C that promotes this process is reusable higher turnover number (TON) than those employed in previously reported methods. results mechanistic studies suggest...
Catalytic methylation of aromatic hydrocarbons using CO2 and H2 as a methylating agent was conducted over combination TiO2-supported Re (Re(1)/TiO2; = 1 wt %) H-β (SiO2/Al2O3 40) in batch reactor. m-xylene performed, this catalyst demonstrated excellent performance for the synthesis methylbenzenes, giving high yield total methylated products (10 57%, calculated on basis m-xylene, respectively), while generating relatively small amounts byproducts such demethylated dearomatized well CO CH4...
Abstract The use of triglycerides as an important class biomass is effective strategy to realize a more sustainable society. Herein, three heterogeneous catalytic methods are reported for the selective one‐pot transformation into value‐added chemicals: i) reductive amination fatty amines with aqueous NH 3 under H 2 promoted by ZrO ‐supported Pt clusters; ii) amidation gaseous catalyzed high‐silica H‐beta (Hβ) zeolite at 180 °C; iii) Hβ‐promoted synthesis nitriles from and 220 °C. These...
Abstract A combined catalyst comprising TiO 2 ‐supported Re (Re(1)/TiO ; Re=1 wt%) and H‐MOR (SiO /Al O 3 =90) was found to promote the methylation of benzene using CO H . This catalytic system exhibited high performance with regard synthesis methylated benzenes gave yields total products (up 52 % benzene‐based yield 42 ‐based yield) under reaction conditions employed in this study ( p CO2 =1 MPa; H2 =5 T =250 °C; t =20 h) a batch reactor. Catalyst screening demonstrated that combination...
Abstract The direct catalytic esterification of amides that leads to the construction C−O bonds through cleavage amide C−N is a highly attractive strategy in organic synthesis. While aliphatic and aromatic alcohols can be readily used for alcoholysis activated unactivated amides, introduction phenols more challenging due their lower nucleophilicity phenolysis amides. Herein, we demonstrate into corresponding phenolic esters using simple heterogenous system based on CeO 2 under additive‐free...
We report a cost-effective, green, and acceptorless dehydrogenative one-pot synthesis of triazines from primary alcohols amidines using an alumina-supported Pt nanoparticle catalyst (Pt/Al 2 O 3 ).
The Cover Feature shows transformations of triglycerides into fatty amines, amides, and nitriles using NH3 H2. More information can be found in the Full Paper by Jamil et al on page 3115 Issue 13, 2019 (DOI: 10.1002/cssc.201900365).
Abstract Invited for the cover of this issue are groups Ken‐ichi Shimizu at Institute Catalysis, Hokkaido University. The image depicts phenolysis amides through C−N bond cleavage reaction catalyzed by CeO 2 . Read full text article 10.1002/chem.201901446
