Rutheniumnanoparticles (Ru NPs) stabilized by phosphine-functionalized ionic liquids (PFILs) were synthesized in an imidazolium-based ionic liquid using H2 as a reductant. Characterization showed well-dispersed particles of about 2.2 nm (TEM) and confirmed the PFIL stabilization of the Ru NPs (NMR). The Ru NPs stabilized by PFILs exhibited excellent activity and switchable chemoselectivity in the

The lithium salts of trityl- and diphenyl-4-pyridylmethyl-hydrazones of both aldehydes and ketones react with electrophiles (alkyl halides, aldehydes, ketones, crotonates) at low temperature to form C-trapped azo compounds ; these Intermediates decompose homolytically with loss of nitrogen below room temperature and can be diverted in a synthetically useful way to alkanes, alkenes, alcohols or saturated

Disclosed are compounds of Formula (I) wherein: one of A and D is —N— and the other of A and D is —C—; or enantiomers, diastereomers, or pharmaceutically-acceptable salts thereof. Also disclosed are methods of using such compounds to modulate the function of glucocorticoid receptor activity and pharmaceutical compositions comprising such compounds.
Ru and Rh nanoparticles (NPs) RuI, RuII, RhI and RhII, stabilised by triphenylphosphine (PPh3) and diphenylphosphinobutane (dppb) were synthesised, characterised and applied as catalysts in the hydrogenation of several aromaticketones. The effects of the nature of the metal and of the stabilising agent on the aryl versus ketonehydrogenation were studied. For Rh NPs, the coordination of arene dominates
