## Abstract The proton NMR spectra of tetraphenylporphyrin, octaethylporphyrin and the analogous chlorins (7,8βdihydroporphyrins) are presented, and the chemical shift changes on chlorin formation are interpreted using a ring current model. In these compounds a general 10% reduction in the ring cur
Reaction of zinc 5,15-bis(3,5-di-tert-butylphenyl)porphyrin and 10,20-di-CF 3 -porphyrins as the minor products. The direct trifluoromethylation is effective for preparation of with S-(trifluoromethyl)-3,7-dinitrobenzothiophene trifluoromethanesulfonate in tetrahydrofuran gave the 10-tri-longer-wave
