Self-condensation - Wikipedia
In organic chemistry, self-condensation is an organic reaction in which a chemical compound containing a carbonyl group (C=O) acts both as the electrophile and the nucleophile in an aldol condensation. It is also called a symmetrical aldol condensation as opposed to a mixed aldol condensation in which the electrophile and nucleophile are ...
Self-condensation-assisted chemical vapour deposition growth of ...
2024年4月29日 · Here, we report the self-condensation-assisted chemical vapour deposition growth of atomically thin MOF single-crystals, yielding monolayer single-crystals of poly[Fe(benzimidazole)2] up to 62 μm...
Self-aldol condensation of aldehydes over Lewis acidic rare …
2021年4月1日 · The self-aldol condensation of aldehydes was investigated with rare-earth cations stabilized by [Si]Beta zeolites in parallel with bulk rare-earth metal oxides. Good catalytic performance was achieved with all Lewis acidic rare-earth cations stabilized by zeolites and yttrium appeared to be the best metal choice.
Self-condensation for enhancing the hydrophilicity of covalent …
2024年10月1日 · Herein, we present a green synthetic approach to synthesize five hydrophilic and non-conjugated linkage with D-π-A system benzoin-based COPs by self-condensation of multiformly monomers. Charge kinetic carrier and femtosecond transient absorption (fs-TAS) demonstrate the efficient charge transport of benzoin-based COPs.

Mechanism of the self-condensation of GlcNH2: insights from …
2017年3月1日 · A detailed reaction mechanism for the self-condensation of GlcNH 2 with the homogeneous catalyst [C 2 C 1 Im][OAc] was revealed by in situ NMR spectroscopy, mass spectroscopy and quantum chemical calculations.
Highly selective self-condensation of cyclohexanone: the distinct ...
2020年10月7日 · HRF5015, a perfluorosulfonic acid resin catalyst with unique pore structures, was investigated in the catalytic self-condensation of cyclohexanone under mild conditions. The morphology of HRF5015 was characterized by transmission electron microscopy (TEM) and atomic force microscope (AFM), and the reaction mechanism was studied by in situ ...
Ultrahigh selectivity self-condensation of cyclohexanone over …
2023年6月12日 · The self-condensation of Cyclohexanone is the first stage in the industrial synthesis of 2-phenylphenol, as well as a reversible Aldol condensation reaction and that can be carried out under acid-catalyzed or base-catalyzed conditions [3, 10, 13].
Formation of biological condensates via phase separation ...
2019年10月4日 · Self-condensation is one of the key features and probably also the most important function of phase separation. Compared with macromolecular complexes formed by traditional interaction mode, a demixed phase enables molecules to be massively enriched into a restricted subcellular region and subsequently to increase their local concentrations by ...
European Journal of Lipid Science and Technology
2018年4月12日 · Based on the herein experimental results and literature data, this article proposes a general mechanism of self-condensation of glycerol to polyglycerol in the presence of alkaline catalysts. The mechanism involves the in situ formation of glycidol and oligo-glycerols with terminal epoxy groups by intramolecular SN 2 substitution reactions. We ...
