Convenient method for preparing benzyl ethers and esters using 2-benzyloxypyridine

Beilstein Journal of Organic Chemistry, 2008
2-Benzyloxy-1-methylpyridinium triflate (1) is emerging as a mild, convenient, and in some cases uniquely effective new reagent for the synthesis of benzyl ethers and esters. This article provides a revised benzyl transfer protocol in which N-methylation

Single-pass transformation of syngas into ethanol with high selectivity by triple tandem catalysis

Nature Communications, 2020
Direct synthesis of ethanol from non-petroleum carbon resources via syngas (CO/H2) is a highly attractive but challenging target. Here, the authors report a triple tandem catalytic system for single-pass conversion of syngas into ethanol with selectivity

Direct conversion of methane to formaldehyde and CO on B2O3 catalysts

Nature Communications, 2020
Partial oxidation of methane to value-added C1 products remains challenging due to the favorable formation of fully-oxidized CO2. Here, the authors show supported B2O3 catalysts with tri-coordinated BO3 units as the active site are highly selective in ...

Quantitative analysis and comparison of the physical properties of O-alkyl and S-alkyl monoethers of glycerol

Journal of Lipid Research, 1969
A homologous series (C10, C12, C14, C16, C18) of synthetic O-alkyl and S-alkyl ethers of glycerol was analyzed by gas-liquid chromatography (GLC) and thin-layer chromatography (TLC), and examined by IR and n.m.r.

New anionic cobalt(III) complexes enable enantioselective synthesis of spiro-fused oxazoline and iodoacetal derivatives

Frontiers in Chemistry, 2022
Anionic salicylimine-based cobalt (III) complexes featuring chiral ligands derived from isoleucine amino acids were used as efficient bifunctional phase-transfer catalysts for electrophilic iodination of enol ethers. The Brønsted acids of these complexes
