The potential of carbonyl-stabilized phosphonium ylides as ligands for novel catalysis was explored. We found that the combination of phosphonium ylides and metal halide salts efficiently catalyzed the reaction of epoxides with carbon dioxide under mild c

Tetraarylphosphonium inner-salts (TAPIS) have been designed, synthesized and verified as recyclable and reusable Lewis base catalysts. The resulted TAPIS catalyst has been successfully applied in Michael addition, cyanation and trifluoromethylation reactions.

The 2-substituted phenylphosphine bidentate hybrid ligands, 2-aminophenyl-, 2-methylaminophenyl-, 2-hydroxyphenyl- and (2-amino-3-methylphenyl)-diphenylphosphine, (1a-d), respectively, and 2-aminophenylmethylphenylphosphine, (1e), were synthesized by reduction of their phenylphosphonium halides, (2a-e)X (X = Cl or Br), with sodium naphthalenide in tetrahydrofuran at -68 deg, or electrochemically at a mercury cathode.The phosphonium salts were prepared by reaction of triphenylphosphine with aryl halide and anhydrous nickel halide at 200 deg.X-Ray diffraction of (2a)2 showed it to have monoclinic space group P21/n, a 10.657(4), b 20.966(3), c 20.422(6) Angstroem, β 101.33(2) deg and Z 4.The structure was refined by a full-matrix least-squares procedure to a final R 0.050 for 3534 reflections with I > 2.5?(I).
