Abstract
Cyclometalation reactions are usually defined as the reactions of metal compounds with conventional substrates, such as benzylamines and 2-phenylpyridines. In contrast, unconventional cyclometalation reactions are the reactions of metal compounds with unconventional base substrates, such as 2-amino-3-picoline, anilines and 2- aminopyridines, and with auxiliary substrates, such as aldehydes and alkynes. Other unconventional cyclometalation reactions also exist, examples include the cyclocarbonylations of metal carbonyl compounds with unsaturated hydrocarbons, such as alkynes, alkenes and aryl compounds; reactions with 2-vinylpyridines; and rollover cyclometalation reactions.
Keywords: 2-vinylpyridine, aminopicoline, aniline, cyclocarbonylation, cyclometalation, rollover, unconventional cyclometalation.

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
