Triphenylcarbonium salt

The addition of electrophilic agents to terminal nitride ligands can be applied to the synthesis of imido complexes. This has been demonstrated with triphenylcarbonium salts and compounds of the formula [Re NC(C6H5)3 X4] (X = C1, Br, F, NCS) have been studied by EPR spectroscopy and show similar spectroscopic features to their [Re NB(C6F5)3 X4] analogues.

Oxidation of 1-substituted 1,2-dihydro-X -phosphorins with mercuric acetate or triphenylcarbonium salts (Markl). 

NO)(=CHCH2R)(PPh3)(NO)] from [ReCp(PPh3)(NO)(CH2CH2R)(PPh3)(NO)] [272], The early examples of the use of triphenylcarbonium salts in organometallic chemistry have been reviewed [273]. 

The acceptor properties are reflected in its poor ability to solvate metal cations and in its capacity to allow complete dissociation of triphenylcarbonium salts the presence of SO3 produced by self dehydration (see below) may be responsible —at least in part—for the acceptor properties.
