- Synthesis and structure of tritylium salts
-
Several tritylium compounds [Ph3C][A] have been isolated by salt metathesis or halide abstraction reactions starting from Ph3C-X (X = halogen) and Lewis acids in good yields (A = BF4, BCl4, AlCl4, GaCl4, PF6, AsF6, SbF6, SbCl6, CHB11H5Cl6, CHB11Cl11, CHB11H5Br6, CF3COO, CF3SO3, N3). The structures of 15 tritylium salts bearing different types of weakly coordinating anions (A-) have been determined. The structures are discussed on the basis of ion pairing versus covalent bond formation and solid-state interactions in comparison with gas-phase data.
