A. Nakano et al., Directly linked dehydropurpurin-porphyrin dyads from Ag(I)-promoted oxidation of meso-phenylethynyl substituted zinc(II) porphyrins, CHEM COMMUN, (19), 2001, pp. 1920-1921
Ag(I)-promoted oxidation of (5,15-diaryl-10-phenylethynylporphyrinato)zinc(
II) complexes in CHCl3 gave directly linked 12,13-dehydropurpurin-porphyrin
dyads, the structures of which were revealed by X-ray analysis.
