✦ Synopsis

Octaethylchlorin forms a violet mono-cation and a deer, blue di-cation in two discrete stages on spectrophotometric titration with trifluoroacetic acid in chloroform solution, and similar results are obtained with chlorophyll derivatives although the colour changes are much less pronounced.

## Abstract Metallo‐tetrahydrobiline __rac__‐**8** was prepared to investigate its cyclization directed to the formation of __N__‐confused chlorins. To achieve the site‐directed selectivity of the cyclization, the 2‐position of __rac__‐**2** was activated by an electron‐withdrawing cyano function a
