Cyclizations of Terminally Substituted a,c-Biladiene Salts to give meso-Substituted Porphyrins
Smith, Kevin M.,Pandey, Ravindra K.
, p. 1229 - 1236 (2007/10/02)
Cyclizations of 1',8'-disubstituted a,c-biladiene salts using copper(II) salts afford the corresponding meso-substituted porphyrins (after removal of copper) along with smaller amounts of the corresponding meso-unsubstituted analogues.For example, the a,c
