Hk. Hombrecher et al., SYNTHESIS AND ELECTROCHEMICAL INVESTIGATION OF BETA-ALKYLOXY SUBSTITUTED MESO-TETRAPHENYLPORPHYRINS, Tetrahedron, 49(38), 1993, pp. 8569-8578
The synthesis of beta-alkyloxy substituted tetraphenylporphyrins is de
scribed. Due to interaction between the beta-alkyloxy substituent and
the meso-phenyl moiety the porphyrins are slightly non planar. The dev
iation from planarity in these compounds is investigated by cyclic vol
tammetry.
