2-Alkyl-6,6-dialkylfulvenes are synthesized by the condensation of monosubstituted 1,3-cyclopentadienes with carbonyl compounds in the presence of pyrrolidine and converted to the corresponding dialkyl-1,3-cyclopentadienes by the addition of nucleophilic reagents lithium aluminum hydride or methyllithium.
