Organosilver species

As for the cyclopropane rearrangement, the reaction probably involved the formation of a cationic silver cationic species followed by regioselective o-bond migration, leading preferentially to the more stable carbocation intermediate that is finally intramolecularly trapped by the organosilver species (Scheme 3.25).39...

Organosilver species and silver salts thus exhibit a wide variety of behaviors, and further work will probably unravel new roles in organic chemistry, especially for the formation of C-C bonds.
