Back Cover: Recent Advances in Azaborine Chemistry (Angew. Chem. Int. Ed. 25/2012)

Ouroboros, from the Greek oura meaning tail and boros meaning eating, is a symbol imbued with great meaning across various diciplines and cultures. For example, the vision of a snake devouring its tail led Kekulé to the structure of the quintessential arene benzene almost 150 years ago. In their Review on page 6074 ff., S.‐Y. Liu and co‐workers summarize recent progress in the development of boron–nitrogen‐containing heteroarenes. Cover illustration: Patrick Blower.
