title: Synthesis of bis- and oligo-gem-difluorocyclopropanes using the olefin metathesis reaction
abstract: Synthesis of six types of novel bis- and oligo-gem-difluorocyclopropanes has been accomplished through the olefin metathesis reaction protocol. Two types of ruthenium-based olefin metathesis catalysts were tested: the ruthenium catalyst coordinated with 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene and tricyclohexylphosphine ligands gave better results than the ruthenium catalyst that coordinated with two tricyclohexylphosphine ligands.
