Mesoporous MCM-41 was used as a support for the uniform dispersion of ruthenium nanoparticles having an average particle size of ～5 nm. The obtained nanocomposite, MCM-41-Ru, was characterized using inductively coupled plasma, transmission electron microscopy, energy dispersive X-ray analysis, X-ray diffraction, and BET surface area measurements. The material was employed as an efficient and recyclable catalyst in the ultrasound-assisted oxidation of arenes. It was observed that ultrasound irradiation in combination with KBrO3 as the oxidant, in the presence of MCM-41-Ru nanoparticles, accelerates the oxidation reaction to afford the desired products in good yields. The recovered catalyst retained activity for successive runs, with a continuous change in the nature of its active sites.

Ahead of the PAC: Polycyclic aromatic compounds (PACs) can be easily accessed by the combination of Suzuki-Miyaura cross-coupling and a [Rh 2(OAc)4]-catalyzed carbene reaction using easily available bis(N-tosylhydrazone)s as intermediates (see scheme; Ts=4-toluenesulfonyl). Copyright
