Özet

The complexes [RhCl(3 n)(MeCN)(n)(CF(3)triphos)](CF3SO3)(n) (n = 1, 2; CF(3)triphos = MeC[CH2P(m-CF3C6H4)(2)](3)) and [M(MeCN)(3) (CF(3)triphos)](CF3SO3)(n) (M = Ru, n = 2; M = Ir, n = 3) are catalyst precursors for some typical acetalization and transacetalization reactions. The activity of these complexes is higher than those of the corresponding species containing the parent ligand MeC[CH2P(C6H5)(2)](3)(Htriphos). Also the complexes [MCl3(tripod)] (tripod = Htriphos and CF(3)triphos) are active catalysts for the above reactions. The complex [RhCl2(MeCN)(CF(3)triphos)](CF3SO3) catalyzes the acetalization of benzophenone.
