On the Negligible Impact of Ruffling on the Electronic Spectra of Porphine, Tetramethylporphyrin, and Perfluoroalkylporphyrins

Autor: and Andrew S. Koch, Alan K. Wertsching, Stephen G. DiMagno

Publikováno v: Journal of the American Chemical Society. 123:3932-3939

In the first part of this paper, the syntheses, structural characterization, molecular modeling, and electronic spectra for planar and nonplanar perfluoroalkylated porphyrins, (R(f))(4)P's, are reported. These studies demonstrate that the intrinsic s

Stability of Pyridiniumylquinones to Aqueous Media: The Formation of Pyridinium−Oxy Zwitterionic Quinones

Autor: Warren Grant Harbison, and Martin de Kort, Barbara A. Roe, Andrew S. Koch, Joshua M. Hubbard

Publikováno v: The Journal of Organic Chemistry. 61:5959-5963

The stability of perpyridiniumyl- and halopyridiniumylbenzoquinones was investigated. Reactions of p-chloranil and p-fluoranil with pyridines, followed by hydrolysis under mild conditions, gave 2,3-dihalo-5-oxy-6-(pyridinium-1‘-yl)-1,4-benzoquinone
