The title synthesis consists of reactions between [(h5-C5H5)TiCl2]2O and substituted cyclopentadienyllithium prepared from 6,6-dialkylfulvene and aryllithium, followed by treatment with hydrochloric acid. The effects of the substituted cyclopentadienyl group and electronic structure of (h5-C5H5)2TiCl2 and [(h5-C5H5)TiCl2]2O on yield of products were studied. Seven alkyl substituted titanocene difluorides were also synthesized.
