Reductive Bergman-Type Cyclizations of Cross-Conjugated Enediynes to Fulvene and Fulvalene Anions: The Role of the Substituent

Various cross-conjugated enediynes undergo "Bergman-type" cycloaromatizations upon reduction with potassium metal, generating anions of fulvenes and fulvalene derivatives. This new anionic cyclization is considerably more facile than the classic Bergman cyclization with linear enediynes, creating highly reactive diradicals at -78 degrees C. Not all cross-conjugated enediynes yield cyclized dianions
Cycloaddition von phenylarsinen an pentadiin-1,4-one-3 und 3-methylenpentadiine-1,4

The radicalic cycloaddition of phenylarsine and trimethylsilylsubstituted phenylarsines to pentadiyn-1,4-ones-3 yields the 2-methylene-arsolene-4-ones-3; these ketones react with diphenylketene to give the substituted 2,3-bis-methylene-arsolenes-4, which undergo thermal electrocyclic reactions. The resulting benzannelated arsolenes are dehydrogenated to the corresponding arsoles, which can be isolated
One-Step Construction of Five Successive Rings by Rhodium-Catalyzed Intermolecular Double [2+2+2] Cycloaddition: Enantioenriched [9]Helicene-Like Molecules
Enantioenriched fluorenone‐containing [9]helicene‐likemolecules have been successfully synthesized through the formation of five successive rings by rhodium‐catalyzed intermolecular double [2+2+2] cycloadditions of 2‐naphthol‐linked tetraynes with dialkynylketones (see scheme; cod=cycloocta‐1,5‐diene). Their unique crystal structures and photophysical properties have also been determined.
