  to give 1‐aminoindane derivatives in high yields with high regio‐ and stereoselectivities. The iridium complex coordinated with a substrate 1,3‐diene displayed high catalytic activity. The reaction proceeds via the direct formation of the aryliridium(I) species from the aromatic aldimine and an iridium(I) acetate species via a concerted metalation‐deprotonation pathway.

  A simple AlCl3‐catalyzed condensation/cyclization cascade process between aldehydes and sulfonamide is reported, in which two new bonds and one five‐membered ring are simultaneously formed with water as the byproduct. This method provides a rapid access to indenamine and 9‐aminofluorene derivatives. Additionally, these products can be transformed into corresponding indanones and fluorenones under the

  By simply heating the mixture of an arylaldehyde and a sulfonylisocyanate in a solvent or in neat form under catalyst- and additive-free conditions, the desired N-sulfonylimine was produced with the release of carbon dioxide. The method is characterized by its unique clean efficiency, convenience, and scalability, but it was reported to fail half a century ago.
