Preparation of Ternary Platinum(II) Complexes with N-(.OMEGA.-Phenylalkyl)-1,2-ethanediamine and 2,2'-Dipyridine and the Effect of the Methylene Chain Length of the N-(.OMEGA.-Phenylalkyl)-1,2-ethanediamine in the Complexes on Intermolecular Interactions with Various Arylsulfonates
Synthesis of 6- to 10-membered ring (E)-hydroxyiminohydroazaazoniabenzocycloalkenes derivative from cyclization of 2-nitromethylene-1-(ω-phenylalkyl)imidazolidine or 2-nitromethylene-1-(ω-phenylalkyl)hexahydropyrimidine in trifluoromethanesulfonic acid
In trifluoromethanesulfonicacid, 2-nitromethylene-1-(ω-phenylalkyl)imidazolidine or 2-nitromethylene-1-(ω-phenylalkyl)hexahydropyrimidine derivatives undergo an intramolecular cyclization to afford (E)-hydroxyiminohydroazaazoniabenzocycloalkenes, in their trifluoromethanesulfonate salt form. The reaction probably occurres via the formation of an electrophilic transient hydroxynitrilium ion (or O-protonated
Preparation of Ternary Platinum(II) Complexes with N-(.OMEGA.-Phenylalkyl)-1,2-ethanediamine and 2,2'-Dipyridine and the Effect of the Methylene Chain Length of the N-(.OMEGA.-Phenylalkyl)-1,2-ethanediamine in the Complexes on Intermolecular Interactions with Various Arylsulfonates
A series of ternary complexes comprised of platinum(II), 2,2′-dipyridine, and N-(ω-phenylalkyl)-1,2-ethanediamine was prepared by varying the number (n) of methylene chain carbons between the phenyl group and one of the amino groups of 1,2-ethanediamine. NMR measurements indicated that intramolecular stacking occurred for n=1 and intermolecular stacking occurred for n=3 for several of the aryl sulfonates.
