摘要

The effectivity of optical switching between anthracene derivatives 3a, b and their intramolecular photocycloadducts 4a, b is impaired by traces of acid. The systematic treatment of 4a, b with an increasing excess of formic acid revealed that—apart from the normal enolether cleavage 4a, b→ 6a, b→ 7a, b—a cleavage with rearrangement of the carbon skeleton can occur: 5b→ 6b′. The driving force is a stability enhancement of the ...
