An efficient catalytic method for fulvene synthesis

The effects of the nature and amount of base, substrate structure, amount of added water and solvent on the condensation of carbonyl compounds with cyclopentadiene in the presence of secondary amines were investigated. Based on these studies, a new efficient and green synthesis of fulvenes was developed.

Tandem Reactions of N,N-Dialkylamides with Organolithium Compounds and Cyclopentadiene. A New Efficient Synthesis of Pentafulvenes

Reactions of N,N-dialkylamides with organolithium compounds followed by addition of cyclopentadiene furnish 6-mono- or 6,6-di-substituted pentafulvenes in moderate to high yields, providing a new and simple pentafulvene synthesis.
