As mentioned inSection 5.2.2.5.2,heterocyclic aminesare versatile ligands which can stabilize low oxidation states of Tc. The TcIIIcompound [TcCl3(PPh3)2(NCCH3)] (412) has proven to be an extremely versatile starting material for complexes containing heterocyclic and nonaromatic mono- and bidenta...
Here we report the potential of synchronous front-face fluorescence spectroscopy in combination with chemometric tools to detect thermal changes in cooked meat. Samples of bovine meat (Longissimus dorsi muscle) were cooked at 66, 90 & 237 °C for 0, 1, 2, 5, 7, and 10 min. Synchronous fr...
Malgré des propriétés électroniques similaires entre les ligands 1M, les activités catalytiques dépendent significativement de la présence, ou non, d’un métal central dans la porphyrine : une conversion de 80–90% de l’iodobenzène est observée avec les métalloporphyrines (M = Ni,...
A new class of enantioselective conjugate addition (ECA) reactions that involve aryl- or alkenylsilyl fluoride reagents and are catalyzed by chiral non-C2-symmetric Cu-based N-heterocyclic carbene (NHC) complexes are disclosed. Transformations have been designed based on the principle that a catalytic...
N-heterocyclic carbenes are a class of persistent carbenes stabilized by adjacent heteroatoms that are part of a heterocycle. They play a central role in multiple enzymatic biosynthetic reactions that involve thiamine diphosphate. Inspired by this biocat
Biodegradation of aromatic and heterocyclic compounds requires an oxidative ring cleavage enzymatic step. Extensive biochemical research has yielded mechanistic insights about catabolism of aromatic substrates; yet much less is known about the reaction m

The values for the ratio of infected cells, or infection ratio, are normalized to the average ratio of infected cells from all negative (1% DMSO) and positive controls (non- infected cells) wells from the same plate to obtain the normalized activity, following the equation WellNA 5 100 3 ...
nonnoble metal electrocatalysts with suppressed side reactions is of vital significance for EAH reactions. In principle, acetylene molecules are electrophilic, while ethylene is nucleophilic10. Accordingly, to suppress the competitive HER, it is desired to enrich the electron density of active sites in...
