(Z)-Tetraphenylbut-2-ene-1,4-diones: facile synthesis, tunable aggregation-induced emission and fluorescence acid sensing

A facile approach to synthesize stereospecific (Z)-aryl-functionalized 1,4-enediones has been presented. The resulting molecules (TPBD-1 and TPBD-2) were demonstrated as a new type of heteroatom-containing AIE-active luminogens with multiple sites for str

Preparation method for cis-butyl-2-ene-1,4-diketone derivative

The invention discloses a preparation method for a cis-butyl-2-ene-1,4-diketone derivative. The preparation method comprises the following steps: dissolving 2-hydroxy-1,2-bis(4-alkoxyphenyl)ethanone (I) into a solvent 1,4-dioxane; under the protection of

Facile Access to Multiaryl-1H-pyrrol-2(3H)-ones by Copper/TEMPO-Mediated Cascade Annulation of Diarylethanones with Primary Amines and Mechanistic Insight

A straightforward approach to an array of multiaryl-1H-pyrrol-2(3H)-ones featuring an α-diarylated all-carbon quaternary center was developed by using diarylethanones and primary amines as the raw materials. A complete mechanism involving a CuO/TEMPO-mediated multistep cascade process with an inherent delicate balance of substituent electronic effect is proposed. Moreover, this class of multiaryl β,γ-unsaturated γ-lactams demonstrates an intriguing aggregation-induced emission effect valuable for potential application in developing luminescent materials.

Thermolysis of selenophene 1,1-dioxides

Selenophene 1,1-dioxides are thermally far labile than the corresponding thiophene 1,1-dioxides. Even heavily substituted tetraphenylselenophene 1,1-dioxide (1a) decomposed, by a process not involving cyclodimerization, when heated above its melting point or heated in refluxing toluene. Thus, the thermolysis of la in refluxing toluene afforded tetraphenylselenophene (2a, 6%), tetraphenylfuran (3a, 71%), (Z)-l,2,3,4-tetraphenyl-2-butene-l,4-dione (Z-4a, 19%), (E)-1,2,3,4-tetraphenyl-2-butene-1,4-dione (E-4a, 4%), SeO2 (23%), and Se (22%), while that of the neat sample gave 2a (5%), Z-4a (78%), E-4a (17%), SeO2 (17%), and Se (29%). Similar results were also obtained on thermolyses of a series of selenophene 1,1-dioxides. The experimental observations (influence of solvents, oxygen, and additive such as diene to the decomposition rate and the presence of induction period) revealed that the mechanism of the decomposition is highly complex. A tentative mechanism that can explain the observed products is presented.

Oxidation of Tetraarylselenophenes and Benzoselenophene with m-Chloroperbenzoic Acid

Oxidation of tetraarylselenophenes with m-chloroperbenzoic acid produces cis-1,2-diaroyl-1,2-diarylethylenes and SeO2 as the principal product, while the oxidation of benzoselenophene affords benzoselenophene 1-oxide.

ANODIC OXIDATION OF DIARYLACETYLENES AND DIARYLDIACETYLENES: ELECTROSYNTHESIS OF DIAROYL-STILBENES AND ACETYLENIC α- AND γ-DIKETONES

Diarylacetylenes and diaryldiacetylenes have been electrooxidized in acetonitrile through the use of a graphite plate anode, thus overcoming a very high passivation.Diarylacetylenes led mainly to 1,2-diaroyl-1,2-diaryl-ethylenes.Anodic oxidation of conjugated diaryldiacetylenes, at the same anode, led to a mixture of acetylenic α- and γ-diketones.This represents the very first synthesis of acetylenic α-diketones Ar-CO-CO-CC-Ar.

Electro-oxidation of Diarylacetylenes and Diaryldiacetylenes

Diarylacetylenes led to 1,2-diaroyl-1,2-diarylethylenes and diaryldiacetylenes led to a mixture of acetylenic α- and γ-diketones, by anodic oxydation in MeCN-LiClO4 on a graphite plate electrode.
