Abstract

When one ring is not enough: A new double cyclization of stilbene derivatives results in benzo[b]fluorenes via dihydronaphthalenes. The presence of a selenium electrophile and a Lewis acid are crucial for the formation of the CC bonds.magnified image

**The large‐scale synthesis of single‐crystal Se nanotubes** (e.g., see Figure) has been realized via a novel micelle‐mediated process, the key to which may be the use of micelles to control the distribution of amorphous Se in solution.
