A retro-style arcade machine needs an oxidant or a proton to be inserted start playing and switch the donating capabilities of novel phosphine ligands orthogonally reversibly. Rh-catalysed hydrosilylation showed that these triggers can influence either rate conversion and/or product distribution. The Japanese kanji for “iron” highlights ferrocene moiety in ligands′ metal complexes. More informa...

This review summarizes synthetic approaches to reusable photocatalytic systems based on visible light-active transition metal complexes with chelating ligands containing pyridyl residues such as 2,2?-bipyridines, 1,10-phenanthrolines, 2,2?:6?,2??-terpyridines and related ligands. The use of these materials in organic synthesis is then discussed focusing 1) most active exhibiting a synergy effec...
