New Chiral Cyclopentadienylrhenium Lewis Acids Featuring Fluorinated Triarylphosphanes and Enhanced Acceptor Abilities − An Unusual Carbon−Fluorine Bond Activation in a Metal Coordination Sphere

Synthesis, chemical reactivity and electrochemical behaviour of mono- and difluoro metallocenes

“…metallocenes with fluorine atoms in side chains and metallocenes with fluorine atom(s) directly bound to the Cp ring. [4][5][6][7] The first group includes for example metallocenes with fluorinated alcohols or two metallocene moieties with a fluorinated bridging unit. [8][9][10][11][12] Such compounds were prepared and have been studied, e.g.…”

Pentamethylcyclopentadienyl rhodium(III) trifluorovinyl phosphine complexes and attempted intramolecular dehydrofluorinative coupling of pentamethylcyclopentadienyl and trifluorovinyl phosphine ligands

“…In contrast to fluorinated aryl and alkyl phosphines [1][2][3][4][5][6][7][8][9][10], fluoroalkenylphosphines have received relatively little attention [11][12][13]. Following the development of a convenient synthetic route to [CF 2 CF] À Li + from the readily available HFC-134a (CF 3 CH 2 F), and subsequent syntheses of trifluorovinylphosphines R 3Àx P(CF CF 2 ) x [14][15][16], a number of complexes of trifluorovinylphosphines with molybdenum [15], platinum [15,17] and gold [15] have been reported over the past decade.…”

Fluoroarylphosphines as ligands

“…The nucleophilic substitution of fluoride by methoxide and thiomethoxide at the para positions of coordinated tris(pentafluorophenyl)phosphine of a cationic rhenium complex was accomplished at low temperatures with high and moderate yields, respectively, (Scheme 10) [129].…”
