Streszczenie

Reaction of [Rh2Cl2(CO)4] with stoichiometric quantities of 1-methyl-1-azonia-3,5-diaza-7-phosphaadamantane iodide (mtpa+I-) in MeOH and H2O yields square-planar [RhI(CO)(mtpa+I-)2] 1 and trigonal-bipyramidal [RhI(CO)(mtpa+I-)3]·4H2O 2, respectively. The complexes are stable in aqueous solution under inert atmosphere and catalyse the hydroformylation and the hydrocarboxylation of alkenes and the hydrogenation of aldehydes and alkenes. An X-ray crystallography study revealed that 2 has a TBPY-5 structure. The coordination around the Rh atom forms a nearly ideal trigonal bipyramid [a=15.705(3) Å, b=13.219(3) Å, c=20.894(4) Å, monoclinic, space group P21/c, Z=4, β=110.72(3)°].
