Ferrocenyl- and cymantrenyl-phenylthioketone react with C5H5^- or <(C5H5)Fe(CO)2>^- anions forming ferrocenyl- and cymantrenyl-phenylfulvene.The latter readily undergoes a Diels-Alder dimerization or a cycloaddition with a starting thioketone or analogous ketone.Crystal structures of two dimeric products were established.
