A trans type of doublyN-confused isomer of NCP (trans-N2CP) was synthesized via N-confused fused porphyrin (NcFP). The aromatic feature of trans-N2CP due to 18pi electronic system is contrasted to the weak aromaticity of cis-derivative. The solid-state structure of trans-N2CP exhibits pi-stacking column, while the Cu(III) complex shows 1-D rodlike hydrogen bonding chain comparable with the zigzag
N-Confused Porphyrin-Bearing <i>m</i><i>eso</i>-Perfluorophenyl Groups: A Potential Agent That Forms Stable Square-Planar Complexes with Cu(II) and Ag(III)
N-Confused porphyrin (NCP) bearing pentafluorophenyl groups at meso-positions, which were obtained from N-confused dipyrromethane in ca. 20% yield, can form Cu(II) complex as well as Ag(III), Ni(II), and Pd(II) complexes. The square-planar structures of all these metal complexes were elucidated by X-ray single-crystal analyses.
Confusion and Neo-Confusion: Corrole Isomers with an NNNC Core
More confused than ever: Three types of N‐confused corroleisomers (NCCs) were synthesized, and the structures of these isomers were revealed by single‐crystal X‐ray crystallography. The position of the confused pyrrole ring in the NCC has a pronounced effect on optical and anion‐binding properties.
A series of 5,10,15‐tris(pentafluorophenyl) doubly N‐confused bilanes were synthesized in a stepwise manner with the aid of sterically demanding N‐protecting groups, in which the difference in reactivity between regular pyrrole and N‐confused pyrrole plays a crucial role in the synthetic strategy. Some doubly N‐confused bilanes were converted into porphyrinoids or a unique 2:2 copper(II) complex with
