Abstract
The evolution of olefin metathesis catalysts throughout the past six decades has been driven by the need to accommodate more complex, more challenging and more sophisticated applications with this elegant and popular synthetic technology. These challenges have led to a myriad of catalyst designs, in particular the Grubbs-type Ru-alkylidene complexes with their superior tolerance of functional groups and high metathesis activity. Over the past decade, stimuli-responsive olefin metathesis catalysts have carved out a niche as catalysts of improved user-friendliness or of a widened applicability range. This Mini-review will highlight the various approaches to harnessing the changes of the physical or chemical environment to produce olefin metathesis catalysts with significantly changed properties.
Keywords: Ruthenium, Olefin metathesis, Polymerization, Reaction control, Organic synthesis.

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
