Abstract
Reaction of the asymmetrically hexa(2-ethylhexyloxy) substituted nickel phthalocyanine PcNi 1 with the pyridine N-oxides 2a-c to afford the nickel phthalocyanine adducts 3a-c containing furopyridine-type ring is described. The adducts are formed via 1,3-cycloaddtion followed by 1,5-sigmatropic rearrangement.
