Abstract
The concept of π-acid catalysis has emerged as a powerful principle for the chemists to create diversity and originality from simple molecules. Carbophilic late transition metals such as gold or platinum have appeared as fascinating catalysts able to activate alkenes, alkynes and other unsaturated derivatives towards anti nucleophilic addition via complexation on a single empty coordination site. Tunable chiral square-planar cationic platinum complexes created by combination of a mono- and a bidentate ligand appear as a new class of highly promising asymmetric catalytic systems. This highlight intends to stress the potential applications in enantioselective catalytic reactions associated with a variety of chiral cationic tricoordinated platinum complexes recently described in the literature.
Keywords: alkene, alkyne, asymmetric catalysis, cationic and carbophilic complexes, cycloisomerization reaction, enyne, Lewis acid, platinum

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
