Hypervalent iodine reactions utilized in carbon-carbon bond formations.

Advances in hypervalent iodine chemistry have put the field on the precipice of a second golden age; the first being pioneered in the 1990s. During that period, C-C bond forming reactions would be published but rarely with the intended goal of developing a C-C bond forming methodology. More recently, the development of hypervalent iodine-guided electrophilic substitution, arylations using hypervalent iodine, and photoredox reactions with hypervalent iodine have shown great progress in the area of C-C bond formation.
