The Synthesis, Properties, and Reactivities of Free-Base- and Zn(II)-N-Methyl Hydroporphyrin Compounds. The Unexpected Selectivity of the Direct Methylation of Free-Base Hydroporphyrin Compounds

Autor: and Bryan D. Steffey, G. Scott Haymond, Scott W. Simerly, Alan M. Stolzenberg

Publikováno v: Journal of the American Chemical Society. 119:11843-11854

The free-base and Zn(II) complexes of N-methyl-β-octaethyl- and meso-tetratolylchlorin and isobacteriochlorin were synthesized and characterized. Direct methylation of free-base hydroporphyrin compounds was unexpectedly selective. Only one of the se

Activation barriers to meso-aryl group rotation in titanyl tetraaryltetrapyrroles. An investigation of the out-of-plane flexibility of hydroporphyrins

Autor: G. Scott Haymond, Alan M. Stolzenberg

Publikováno v: Inorganic chemistry. 41(2)

The free-base and titanyl (Ti(IV)O) complexes of meso-tetratolyl- and meso-tetra(3,5-xylyl)hydroporphyrins were synthesized and characterized. Metalation of the hydroporphyrins with titanium was achieved by reaction of the lithium salts of the hydrop
