Reverse Arene Sandwich Structures Based upon 蟺-Hole路路路[M(II)] (d8 M = Pt, Pd) Interactions, where Positively Charged Metal Centers Play the Role of a Nucleophile was written by Rozhkov, Anton V.;Krykova, Mariya A.;Ivanov, Daniil M.;Novikov, Alexander S.;Sinelshchikova, Anna A.;Volostnykh, Marina V.;Konovalov, Mikhail A.;Grigoriev, Mikhail S.;Gorbunova, Yulia G.;Kukushkin, Vadim Yu.. And the article was included in Angewandte Chemie, International Edition in 2019.Formula: C5F5N The following contents are mentioned in the article:
[Pt(tpp)] (H2tpp = tetraphenylporphyrin), [M(acac)2] (M = Pd, Pt, Hacac = acetylacetone), and [Pd(ba)2] (Hba = benzoylacetone) were co-crystallized with highly electron-deficient arene systems to form reverse arene sandwich structures built by 蟺-hole-[M(II)] (d8M = Pt, Pd) interactions. [Pt(tpp)]路2C6F6 is monomeric, whereas the diketonate 1:1 adducts form columnar infinity 1-dimensional-stack assembled by simultaneous action of both 蟺-hole-[M(II)] and C-F interactions. The reverse sandwiches are based on noncovalent interactions and calculated ESP distributions indicate that in 蟺-hole-[M(II)] contacts, [M(II)] plays the role of a nucleophile. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Formula: C5F5N).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine has a conjugated system of six 蟺 electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H眉ckel criteria for aromatic systems. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Formula: C5F5N
