摘要

The reaction of the antiaromatic [28]trithiahexaphyrin (TTHP) with Cu~I in DMF gives a novel fused-ring trithiahexaphyrin with the elimination of a chloride on a dichlorophenyl ring and bond formation to the outward oriented pyrrolic nitrogen to form a 5,5,6-tricyclic internal ring system. The NMR spectra, which display characteristics of an antiaromatic compound, agree with the proposed structure. Meanwhile, reactions of TTHP with amines in the presence of Cu~I give amino-group-inserted hexaphyrins with the amino-group-inserted hexaphyrins with the amino nitrogen joined to a beta-thiophenic carbon and the alpha-carbon of the alkylamine cyclized to the inward pyrrolic nitrogen to form a 5,7,5-tricyclic rings. The crystal structure of the fused-ring product indicates a rectangular geometry with a tilted tricyclic ring system, while the ring-modified TTHP-DMA complex gives a triangular trithia-hexaphyrin core. This report demonstrates methods to incorporate functionalized heterocyclic rings into expanded porphyrins.
