Reproducible proton chemical shifts in the porphyrin series are obtained when the spectrum is measured in chloroform using the zinc (11) complex of the porphyrin in the presence of an excess of pyrrolidine. This method is specifically demonstrated for the case of 2,4-dicyanodeuteroporphyrin-M dimeth
Proton NMR data for a number of l-.IZ-4-Y-3,5-dimethylbenzenc?s and l-X-2-Y-4-Z-3,5-dimethylbenzenc?s are presented. The proton chemical shifts of the methyl groups at positions 3 and 5 are mainly affected by the ring current effect of the snbstituents. Thii conclusion was strongly supported by the
