Reactions of cyclopentadienes with phorone

Reactions of different cyclopentadienes with phorone were studied. Nonsubstituted and monosubstituted cyclopentadienes form annelation products, viz., 4,4,8,8-tetramethyl-1,3a,4,5,6,7,8,8a-octahydroazulen-6-ones.

General synthetic route to substituted bis(cyclopentadienyl)- and bis(indenyl)methanes

Several substituted bis(cyclopentadienyl)- and bis(indenyl)methanes were synthesized directly from the corresponding cyclopentadienes (indenes) and ketones in KOH/DME two-phase mixture.
