Bis-olefin-rhodium(I) complexes of a tripod ligand with an O,O,O-donor set

摘要: Abstract The organometallic anion [(C5H5)Co{P(O)(OC2H5)2}3]− reacts as a tridentate oxygen ligand L− with [{RhCl(diolefin)}2] (diolefin = 1,5-cyclooctadiene, norbornadiene, tetrafluorobenzobarrelene, trimethyltetrafluorobenzobarrelene, duroquinone) and [{RhCl(C2H4)2}2] in hexane or acetone the presence of AgClO4 to give air stable compounds type [LRh(diolefin)] [LRh(C2H4)2]. These novel five-coordinate Rh1 complexes are fluxional molecules. They have been characterized by elemental analysis, 1H NMR, IR mass spectroscopy.
