found to be an excellent catalytic system for the chemoselective transfer hydrogenation of nitro-compounds to primary amines. Under mild conditions a series of nitro-compounds containing a variety of sensitive functional groups including aldehydes, esters, cyano, and nitrine were reduced to their corresponding amines in good to excellent yields with no byproduct.

Herein we report the design and synthesis of a series of simple phenol amide ERRγ agonists based on a hydrazone lead molecule. Our structureactivityrelationship studies in this series revealed the phenol portion of the molecule to be required for activity. Attempts to replace the hydrazone with more suitable chemotypes led to a simple amide as a viable alternative. Differential hydrogen-deuterium

The bis(cyclometalated)iridium complex ((Xy)C(∧)C:)(C(∧)N)IrOAc (2d) ((Xy)C(∧)C: = a cyclometalated N-xylyl-N'-methylperimidine-carbene ligand and C(∧)N = a 2-pyridylphenyl ligand), reacted with 2 equiv of Et3SiH to give an iridium hydridecomplex, (L(4))(C(∧)N)Ir(H)(SiEt3) (8d) (L(4) = N-CH3, N-3,5-(CH3)2C6H3 perimidine), via
Encapsulation of Pd(II) into superparamagnetic nanoparticles grafted with EDTA and their catalytic activity towards reduction of nitroarenes and Suzuki-Miyaura coupling
Fe3O4@EDTA–Pd(II) was screened for the Suzuki reaction and reduction of nitrocompounds in water. The Pd content of the catalyst was measured to be 0.28 mmol Pd g−1. In addition, the Fe3O4@EDTA–Pd catalyst can be easily separated and recovered with an external permanent magnet. The anchored solid catalyst can be recycled efficiently and reused five times with only a very slight loss of catalytic activity
