Preparation and 19F NMR spectra of some fluoroolefin complexes of rhodium(I)

Add time:07/18/2019    Source:sciencedirect.com

The fluoroolefin complexes Rh(dpm)(C2H4)(CF2CFX), (dpm = dipivaloylmethanato, X = F, CF3, Cl or Br) have been prepared. Triphenyl-phosphine, -arsine and -stibine displace ethylene from these complexes to give complexes of the type Rh(dpm)(CF2CFX)(L). 19F NMR studies are consistent with a structure in which the substituent X is in an outside position with respect to the ethylene or ligand L.
