Mechanochemical transformation of tetraaryl[3]cumulenes to benzofulvenes via electrophilic iodocyclization†
We demonstrate solvent-free mechanochemical iodocyclization of tetraaryl[3]cumulenes using N-iodosuccinimides as the first example of the molecular transformation of cumulenes based on mechanochemistry. This mechanochemical reaction provides the corresponding benzofulvenes in good yields, overcoming the limitation of conventional methods using organic solvents.
