Ruthenium(II) Catalyzed Regiospecific C-H/O-H Annulations of Directing Arenes via Weak Coordination.

Organic letters

Banerjee A, Santra SK, Mohanta PR, Patel BK.
PMID: 26529054
Org Lett. 2015 Nov 20;17(22):5678-81. doi: 10.1021/acs.orglett.5b02967. Epub 2015 Nov 03.

Ruthenium(II) catalyzed oxidative C-H/O-H annulations have been demonstrated using two different directing arenes viz. 2-arylquinolinone and 2-arylbenzoxazinone with internal alkynes. Regiospecific annulations have been observed for both directing arenes via the assistance of weaker carbonyl oxygen in the presence...

Electrical and thermal transport properties of intermetallic RCoGe2 (R = Ce and La) compounds.

Nanoscale. 2014 Jan 07;6(1):565-71. doi: 10.1039/c3nr05256g. Epub 2013 Nov 18.

Atomic force microscopy with chemically sensitive tips was used to investigate the hydrophobic and electrostatic interaction forces of a stimuli-responsive adhesive polymer, and their dynamic changes in response to water immersion and salt concentration. Block copolymer-filled coatings were obtained...

Porous Ni-Mn oxide nanosheets in situ formed on nickel foam as 3D hierarchical monolith de-NO(x) catalysts.

PMID: 24861850
Nanoscale. 2014 Jul 07;6(13):7346-53. doi: 10.1039/c4nr00475b.

In this work, we successfully in situ decorated nickel foam with porous Ni-Mn oxide nanosheets (3DH-NM/NF) as 3D hierarchical monolith de-NOx catalysts via a simple hydrothermal reaction and calcination process. The catalysts were carefully examined by X-ray diffraction, scanning...
