Inside Cover: The Synthesis and Properties of Free‐Base [14]Triphyrin(2.1.1) Compounds and the Formation of Subporphyrinoid Metal Complexes (Chem. Eur. J. 16/2011)

Abstract

A series of free‐base [14]triphyrin(2.1.1) compounds have been prepared in yields up to 35 % based on a modified Lindsey method. The use of BF3⋅OEt2 as a catalyst and its concentration relative to the pyrrole and aldehyde precursors are critical factors in [14]triphyrin(2.1.1) formation. Retro‐Diels–Alder reactions were used to prepare [14]tribenzotriphyrin(2.1.1) and [14]trinaphthotriphyrin(2.1.1) compounds. For more details see the Full Paper by Z. Shen, H. Yamada, N.
