Jas. Cavaleiro et al., SYNTHESIS AND CHARACTERIZATION OF NEW 2-DIAZO-3-OXO-5,10,15,20-TETRAPHENYLCHLORINS, Heterocyclic communications, 3(3), 1997, pp. 253-261
The Cu and Ni derivatives of beta-amino-5,10,15,20-tetraphenylporphyri
n react with sodium nitrite in THF by formation of 2-diazo-3-oxod,10,1
5,20-tetraphenylchlorins. The spectroscopic properties and some electr
ochemical properties of the synthesised compounds were investigated.
