Highly fluorescent aryl-cyclopentadienyl ligands and their tetra-nuclear mixed metallic potassium-dysprosium clusters

Two alkyl substituted triaryl-cyclopentadienyl ligands [4,4′-(4-phenylcyclopenta-1,3-diene-1,2-diyl)bis(methylbenzene) (1) and 4,4′,4′′-(cyclopenta-1,3-diene-1,2,4-triyl)tris(methylbenzene) (2)] have been synthesized via cross-aldol condensation followed

Iridium(I)-Catalyzed C-C and C-N Bond Formation Reactions via the Borrowing Hydrogen Strategy

Iridium(I) complexes having an imidazol-2-ylidene ligand with benzylic wingtips efficiently catalyzed the β-alkylation of secondary alcohols with primary alcohols and acceptorless dehydrogenative cyclization of 2-aminobenzyl alcohol with ketones through a borrowing hydrogen pathway. The β-alkylated alcohols, including cholesterol derivatives, and substituted quinolines were obtained in good yields by using a minute amount of the catalyst with a catalytic amount of NaOH or KOH under the air atmosphere, liberating water (and H2 in the case of quinoline synthesis) as the sole byproduct. Notably, this system demonstrated turnover numbers of 940 000 (for β-alkylation of secondary alcohols with primary alcohols by using down to 0.0001 mol % = 1 ppm of the catalyst) and 9200 (acceptorless dehydrogenative cyclization of 2-aminobenzyl alcohol with ketones).

Direct synthesis of functionalized PCN-333 via linker design for Fe3+ detection in aqueous media

A new luminescent mesoporous metal-organic framework (PCN-604) was successfully synthesized from trimetric clusters, Al3(O)(CH3COO)6, and pyridine-based tritopic linkers, 4,4′,4′′-(pyridine-2,4,6-triyl)tribenzoate (PTB), v

A direct green route towards the synthesis of 2-aroyl-3,5-diarylthiophenes from 1,5-diketones

The synthesis of 2-aroyl-3,5-diarylthiophenes has been achieved from various 1,5-diketones with elemental sulphur and morpholine under efficient microwave conditions. The reaction follows a green protocol involving solvent-free conditions, short reaction time, and simple work-up avoiding chromatographic purification.

Copper-catalyzed synthesis of 1,3,5-triarylpentane-1,5-diones from α,β-unsaturated ketones

An efficient method for copper catalyzed synthesis of 1,3,5-triarylpentane-1,5-diones using α,β-unsaturated ketones as unique starting materials is described. The protocol offers several advantages such as simple, inexpensive reagents, mild reaction condi

Spectral studies of multi-branched fluorescence dyes based on triphenylpyridine core

A series of novel triphenylpyridine-containing triphenylamine derivatives have been carefully designed and prepared in good yields using the stepwise route reactions. The relationship of photoluminescence property and structure of compounds 9-13 was syste

A facile synthesis and properties of multicarbazole molecules containing multiple vinylene bridges

Multibranched π-conjugated materials and hyperbranched polymers have received considerable interest in both academic research and industrial applications because of their unusual molecular structures and properties. In this communication, we provide an efficient approach to synthesize two novel π-conjugated multibranch compounds, which have good solubility and are nanosize (about 5 nm). The double bonds of the multibranch compounds are synthesized using solvent-free Wittig-Horner-Emmons reactions. The reaction conditions are simple and mild. Their optical properties are discussed too. Copyright
