Abstract
Neoconfusion: In contrast to metal ligation by dipyrrin (see scheme, left), N-confused dipyrrin undergoes cyclomerization with various metal salts to form NCNCNC and NCNCNCNC expanded norroles (see scheme, right), novel isomers of 24 π rosarin and 32 π octaphyrin with C-N linked bipyrrole units with near-planar conformations in the solid state. They also exhibit paratropic ring-current effects typical of antiaromatic porphyrinoids.
