原始语种摘要: Abstract(#br)Chiral, bidentate phosphane ligands, so-called PP ligands, are most frequently synthesized by reacting chiral ditosylates with diarylphosphanide ions.(#br)To use the P(CF 3 ) 2 − ion in nucleophilic substitution reactions, it is necessary to reduce the negative hyperconjugation, which is associated with a C–F activation. For this reason we synthesized different bis(trifluoromethyl)phosphanido complexes of mercury, silver and tungsten and investigated their use in nucleophilic substitution reactions. The most reactive compound, resulting from this study so far, is the pentacarbonylbis(trifluoromethyl)phosphanidotungstenate, [W{P(CF 3 ) 2 }(CO) 5 ] − , which exhibits nearly the same bonding situation for the P(CF 3 ) 2 unit as in the free P(CF 3 ) 2 − ion. For use in synthesis...
