High-valent transition metal corrolazines

Oxygen Atom Transfer

“…In the context of OAT and high-valent complexes, the past few years have witnessed substantial advances in metal corrole and corrolazine complexes. 48,49 Both macrocycles are ring-contracted porphyrinoids. This reduction in one core atom makes the fully deprotonated ligands trianionic, creating stronger s-donation.…”

“…The mechanism under catalytic reactions and the role of Mn V (O) in OAT continue to be a subject of discussion in the literature. 51,49 The Cr III (tpfc) complex reacts with molecular oxygen (O 2 ) to generate Cr V (O)(tpfc). The latter can transfer an oxygen atom to organic phosphines and norbornene, for example, enabling catalytic oxidations with O 2 .…”

Bis-picket-fence corroles

“…1), and their metal complexes has been a fast growing field of research stimulated by their intriguing electronic structures and their numerous potential applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The basis for this development was provided by the introduction of new straightforward syntheses for mesoarylsubstituted corroles [15][16][17][18][19][20][21].…”

Norcorrole: Observation of the Smallest Porphyrin Variant with a N4 Core

“…[2] In addition, porphyrinoids with contracted cavities, and in particular metal chelates of those, show remarkable metric and electronic features. [3] Due to the increasing ring strain upon contraction of the core, however, only corrole [4] and a small number of other macrocycles [5,6] from this subgroup have been studied in more detail.…”
