The synthesis of a new ring structure, octaethylbenzochloracene (6), derive
d from octaethylporphycene is reported. A viable route to the benzochlorace
ne is shown and parallels the transformation of porphyrin to benzochlorin.
Octaethylbenzochloracene's spectral data shows a unique UV-vis spectrum and
an interesting NMR spectrum. Unfortunately, an attempt to synthesize the a
nalogous purpurin derivative, purpuracene (8), failed. Copyright (C) 2001 J
