PROBLEM TO BE SOLVED: To provide an adsorbent produced using a biomass residue, a method for producing the adsorbent, and a method for producing an alcohol or organic acid using the adsorbent.早川 智基奥田 直之
The reactivities of unsaturated compounds in reactions with alcohols fall along the series; dimethyl maleate > methyl acrylate > allyl alcohol ≥ 1-alkenes. 1-Hydroxyalkyl radicals formed from aliphatic alcohols are nucleophilic in character.DOI: 10.1007/BF01176038 年份: 1967 ...
Since we focus on tracing the esterification reaction pathway, we limited the searched reaction space to bimolecular reactions (excluding dimerization reactions) and restricted the reactive sites to carboxylic acid and alcohol groups. This operator-induced steering was carried out by applying the STEERING...
It is an organometallic reaction in which an alkyl halide (chloride, bromide, or iodide) reacts with a carbonyl compound in the presence of metals such as Mg, Al, Zn, Sn, In, Sm, Ba, or their salts to form a primary, secondary, or tertiary alcohol. ...
Theoretical investigations of this reaction are challenging because of intersystem crossing between singlet and triplet surfaces – ∼45% of reaction products are obtained via intersystem crossing of a pre-product complex – which demands experimental determinations of product branching. Here we report ...
This required us to develop our own synthesis of trans-isogeranic acid shown in Scheme 7. Sign in to download full-size image Scheme 7. The synthesis deserves a few comments. The first step of the sequence is a Negishi coupling between homopropargylic alcohol and 1-bromo-3-methyl-but-2...

CH3CH2Ϫ ϩ Hϩ CH3CH3 ORGANIC REACTION MECHANISMS 7 A subtle but important point must be made before we can extend our understanding of acid–base chemistry to the reaction between a Grignard or alkyllithium reagent and a carbonyl group. The data in Table O3.1 reflect the strengths of...
Once a catalytic reaction occurs, it must be possible to easily transfer generated holes or electrons to the conductive frame; thus, engineering of the energy levels between the catalyst materials and the conducting frame should be considered and the electron or hole pathway along the non-...
The discovery of highly enantioselective catalysts and elucidating their generality face great challenges due to the complex multidimensional chemical space of asymmetric catalysis and inefficient screening methods. Here, we develop a general strategy for ultra-high-throughput mapping of the chemical space ...
