Huebscher, Joerg published the artcileSynthesis and Structural Characterization of Ethynylene-Bridged Bisazines Featuring Various α-Substitution, HPLC of Formula: 1059705-07-5, the publication is Journal of Heterocyclic Chemistry (2015), 52(4), 1062-1074, database is CAplus.

A series of bispyridines e.g., I and bispyrimidines e.g., II showing the heterocycles attached to both ends of an ethynylene unit and being -substituted with chloro, tert-butylthio, and methoxy groups have been synthesized via cross-coupling technique and their crystal structures were studied by X-ray diffraction anal. Supramol. interactions of C-H···N and π···π stacking type were found to largely dominate the structures according to the compound species. A trial was given to deduce the markedly differing temperatures of melting among the compounds from special features of the crystal structures.

Kolli, Murali Krishna published the artcilePd-PEPPSI-IPent^Cl: a new highly efficient ligand-free and recyclable catalyst system for the synthesis of 2-substituted indoles via domino copper-free Sonogashira coupling/cyclization, Synthetic Route of 1059705-07-5, the publication is New Journal of Chemistry (2017), 41(16), 8187-8195, database is CAplus.

A pyridine-containing decidedly resourceful Pd-N-heterocyclic carbene complex, Pd-PEPPSI-IPentCl (PEPPSI = pyridine enhanced precatalyst preparation, stabilization, and initiation), prepared and used as a first class recyclable catalytic system for the synthesis of 2-substituted indoles I [X = H, Boc; R¹ = H, 5-OMe, 6-i-Pr, 6-Cl, 5-NO₂, 5,7-di-NO₂; R² = Ph, 4-ClC₆H₄, 2-naphthyl, pyrimidin-5-yl, etc.] via domino copper-free Sonogashira coupling/cyclization. The catalyst showed a greater performance in the cascade reaction of various 2-bromo anilines with different terminal aromatic acetylenes under mild (60 °C) and green conditions (ethanol:water) even in the absence of a copper catalyst and an inert atm. It was confirmed that 0.1 mol% of the catalyst was sufficient, recyclable and could be reused up to six cycles.
