, and further reaction with palladium(II) acetate gave stable organometallic derivatives. The X-ray crystal structure of a palladium(II) benziporphyrin showed that the system deviates significantly from planarity. Although the benzitripyrranes failed to give stable macrocyclic products with furan or thiophene dialdehydes, they afforded tetraphenyl heterobenziporphyrins upon reaction with diphenyl-substituted

Aromatic aldehydes, including azulenecarbaldehydes, have been shown to react with an indene enamine derivative in the presence of dibutylboron triflate to give stable fulvene aldehydes. 1,3-Azulenedicarbaldehyde afforded a fulvene dialdehyde under these conditions, and this reacted with a dipyrrylmethane to give a 22-carbaazuliporphyrin. This adj-dicarbaporphyrinoid showed significant diatropic character
