First report of synthesis of organo-functionalized triethoxysilanes via knoevenagel condensation approach

20-Jun-2018 | Gurjaspreet Singh; Akshpreet Singh; Kavita Chowdhary; Pinky Satija, New Journal of Chemistry, 2018

The synthesis of organo-functionalized triethoxysilanes (OTES) has many recognized pathways; however, no study has been reported on their preparation via knoevenagel condensation. The present work involves synthesis of organo-functionalized triethoxysilanes using this unacclimated green ...

Hf-based Metal-Organic Frameworks as acid-base catalysts for the transformation of biomass-derived furanic compounds into chemicals

20-Jun-2018 | Avelino Corma; SERGIO ROJAS; Pilar García-García, Green Chemistry, 2018

Hf-based metal-organic frameworks (MOFs) are reported here as heterogeneous catalysts for the highly selective and efficient cross-aldol condensation of biomass-derived furanic carbonyls with acetone under mild reaction conditions with near quantitative yields. NMR studies with isotopically ...

N,1,4-Tri(4-alkoxy-2-hydroxybenzyl)-DAZA: Efficient one-pot synthesis and labelling with 68Ga for PET liver imaging in ovo

20-Jun-2018 | Julia Greiser; Christian Kuehnel; Helmar Görls; Wolfgang Weigand; Martin Freesmeyer, Dalton Transactions, 2018

We report the isolation of a new type of 1,4-diazepan-6-amine (DAZA)-based ligand. Condensation of aldehydes with DAZA gives a novel class of 1,5-diazabicyclo[3.2.1]octanes in nearly quantitative yields. Subsequent reductive cleavage of these bicyclic aminal species with sodium borohydride ...

An uncondensed lignin depolymerized in the solid state and isolated from lignocellulosic biomass: A mechanistic study

12-Jun-2018 | Ning Li; Yanding Li; Chang Geun Yoo; Xiaohui Yang; Xuliang Lin; John Ralph; Xuejun Pan, Green Chemistry, 2018

This study demonstrated that lignin could be efficiently depolymerized in the solid state with minimal condensation and separated from biomass with high purity by dissolving and hydrolyzing cellulose and hemicelluloses, using an acidic lithium bromide trihydrate (ALBTH) system under mild ...

Versatile catalysis of Iron: tunable and selective transformation of biomass-derived furfural in aliphatic alcohol

12-Jun-2018 | Zhenya Zhang; Xinli Tong; Haigang Zhang; Yongdan Li, Green Chemistry, 2018

Iron-catalyzed efficient valorization of biomass-derived furfural (FUR) in aliphatic alcohols is developed in which the product selectivity can be simply regulated by varying the gas atmosphere. In the presence of molecular oxygen, the oxidative condensation of FUR with ethanol occurs and the ...

CaMnAl-hydrotalcite solid basic catalyst toward aldol condensation reaction with a comparable level to liquid alkali catalysts

12-Jun-2018 | Weihan Bing; Huimin Wang; Lei zheng; Deming Rao; Yusen Yang; Lirong Zheng; Bin Wang; Yangdong Wang; Min Wei, Green Chemistry, 2018

In a number of heterogeneous catalysis processes, promotion effect toward active sites is of vital importance and remains a challenge to obtain largely-improved catalytic performance. Herein, rehydrated Ca4MnxAl-layered double hydroxides (denoted as re-Ca4MnxAl-LDH) were prepared based on a ...

Pressure-induced switching properties of the iron(III) spin-transition complex [FeIII(3-OMeSalEen)2]PF6

06-Jun-2018 | J. Laisney; H. J. Shepherd; L. Rechignat; G. Molnár; E. Rivière; M.-L. Boillot, Physical Chemistry Chemical Physics, 2018

We investigated the effect of an externally applied pressure on the iron(iii) Schiff-base compound [Fe(3-OMeSalEen)2]PF6 (H-3-OMeSalEen, condensation product of 3-methoxy-substituted salicylaldehyde and N-ethylethylenediamine), which at ambient pressure displays a thermal spin transition with a 3 ...

Acetylacetonato-based pincer-type nickel(II) complexes: Synthesis and catalysis in cross-couplings of aryl chlorides with aryl Grignard reagents

05-Jun-2018 | Erika Asano; Yuki Hatayama; Nobutaka Kurisu; Atsufumi Ohtani; Toru Hashimoto; Youji Kurihara; Kazuyoshi Ueda; Shinji ..., Dalton Transactions, 2018

In this work, three different types of acetylacetonato-based pincer-type nickel(II) complexes (2) were prepared. Complex 2a possessed the tridentate ONN ligand, which was constructed by the condensation reaction of acetylacetone with N,N-diethylethylenediamine. Complex 2b contained the PPh2 donor ...
