Abstract
Ytterbium triflate, Yb(OTf)3, is a versatile Lewis acid that has high catalytic activity in many organic reactions, including aldol, Michael, Mannich, Friedel-Crafts, Diels-Alder, and some other types of reactions. Less than 10 mol% of Yb(OTf)3 is normally sufficient for most organic transformations and can be recovered and re-used without loss of catalytic activity. In addition, Yb(OTf)3 is very stable and its catalyzed reactions can be carried out in both organic solvents and aqueous conditions.
Keywords: Ytterbium triflate, Catalyst, Aldol condensation, Michael addition, Mannich reaction, Friedel-crafts, Diels-alder.

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
