“…Anand and co-workers have been involved in the synthesis of large porphyrin-like macrocycles with a view to studying concepts such as aromaticity and anti-aromaticity (Panchal et al, 2016), (Gopalakrishna et al, 2014). Panda and co-workers have been working on various porphyrin-based macrocycles including isomeric porphyrins (Sarma et al, 2015).…”

“…Very recently, Sarma et al reported an unprecedented cisbimetallic complex of dinaphthoporphycene 6d, namely [Pd 2 (μ-6d)(μ-OAc) 2 ] 9 (Figure 3), wherein two palladium atoms coordinate to the core nitrogens of the macrocycle on the same side. 45 They are closely held together (Pd−Pd, 2.67 Å) by two bridging acetate ligands, exhibiting significant metal−metal bonding interactions (bond order 0.18 evaluated by NBO analysis). The importance of this outcome could be gauged from the fact that this type of complexation mode had been neither sought-after (including computational studies) nor proposed in the literature.…”

Compared to porphyrin, its isomeric, expanded, and contracted analogues are less well explored. This contrast is found to be even more drastic in the case of their peripherally annulated counterparts. Nevertheless, the chemistry of annulated isomeric, expanded, and contracted porphyrins started flourishing recently with considerable efforts over the past few years, as evidenced by an increasing number of publications. While keeping the essence of porphyrins, these annulated versions exhibit quite unique properties that have no precedence in their nonannulated counterparts. An in-depth update of research carried out so far in this emerging area will be presented in this review.

Tetraaryl‐21,23‐dirhodaporphyrin and a series of related monorhodaporphyrins have been obtained by tellurium‐to‐rhodium exchange in a reaction of tetraaryl‐21,23‐ditelluraporphyrin with [RhCl(CO)2]2. These organometallic metallaporphyrins contain rhodium(III) centers embedded in rhodacyclopentadiene rings, incorporated within the porphyrin frames. The skeletons of 21,23‐dirhodaporphyrin and 21‐rhoda‐23‐telluraporphyrin are strongly deformed in‐plane from the rectangular shape typical for porphyrins, due to rhodium(III) coordination preferences, the large size of the two core atoms, and the porphyrin skeleton constrains. These two metallaporphyrins exhibit fluxional behavior, as studied by 1H NMR and DFT, involving the in‐plane motion and the switch of the rhodium center(s) between two nitrogen donors. A side product detected in the reaction mixture, 21‐oxa‐23‐rhodaporphyrin, results from tellurium‐to‐oxygen exchange, occurring in parallel to the tellurium‐to‐rhodium exchange. The reaction paths and mechanisms have been analyzed. The title 21,23‐dirhodaporphyrin contains a bridged bimetallic unit, Rh2Cl2, in the center of the macrocycle, with two rhodium(III) ions lying approximately in the plane of the porphyrinoid skeleton. The geometry of the implanted Rh2Cl2 unit is affected by macrocyclic constrains.
