Facile Synthesis of 1,3,5-Triarylbenzenes and 4-Aryl-NH-1,2,3-Triazoles Using Mesoporous Pd-MCM-41 as Reusable Catalyst
We report mesoporous nano-Pd-MCM-41 catalyzed rapid and efficient synthesis of 1,3,5-triarylbenzenes via de-nitrative cyclotrimerization of β-nitrostyrenes. All the reactions were very fast and high yielding. The Pd-MCM-41 was also very effective in catalyzing de-nitrative [3+2] cycloaddition of β-nitrostyrenes with TMSN3 to synthesize 4-aryl-NH-1,2,3-triazoles. The catalyst was reused at least up to eight times with minimum loss of catalytic activity.

Triple condensation of aryl methyl ketones catalyzed by amine and trifluoroacetic acid: Straightforward access to 1,3,5-triarylbenzenes under mild conditions
An efficient triple condensation reaction of aryl methyl ketones catalyzed by ethylenediamine and trifluoroacetic acid was reported. A broad scope of 1,3,5-triarylbenzenes was obtained in good to excellent yields. The reaction provides a novel and practical approach to access organic materials of polycyclic aromatic hydrocarbons under mild conditions.

Synthesis and functional properties of symmetrically naphthyl-Based oligoarylenes with high glass-transition temperatures
Symmetrically naphthyl-based π-conjugated oligoarylenes, OPP(4)Ph-TNp, OPP(4)An-TNp and OPP(4)OXTNp have successfully been synthesized by a divergent approach using Pd-catalyzed Suzuki cross-coupling reaction of diiodo- or dibromo-oligoarylene and arylboronic acid as a key step. Their optical, electrochemical and thermal properties have also been characterized. These newly synthesized naphthyl-based oligoarylenes show highly morphological (Tg 149-187 °C) and thermal (Tdec 509-597 °C) stabilities as well as exhibit potential applications in optoelectronic fields.

Highly selective biaryl formation by the cyclooligomerization of arylethynes catalyzed by rhodium and ruthenium porphyrins
Rhodium and ruthenium porphyrins catalyze the one-pot formation of biaryl derivatives from arylethynes with high selectivity, giving interesting derivatives not easy to obtain using other different methods; the porphyrin catalysts can be recovered and reu
