Abstract
In continuation of our research in cyclopentadienylalkylphosphane nickel chelates with secondary phosphane tethers the first cationic representatives of this class of compounds are reported. These were obtained by reaction of the respective bromo complex with tris(4-trifluoromethylphenyl)phosphane as well as with a number of alkyl and aryl isonitriles in the presence of indium tribromide. This Lewis acid is crucial for the success of the reactions leading to the respective tetrabromoindate salts. The compounds were characterized spectroscopically, including rare 14N, 13C couplings being observed. Finally, deprotonation experiments are reported, which provide some evidence for deprotonation taking place, although the expected phosphinidene chelates could not be isolated due to rapid decomposition.
