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
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.
