    Description / Table of Contents: Transition Metal Carbene Complexes, LXXIV. Reversible Addition of Tertiary Phosphines on Pentacarbonyl(methoxymethylcarbene) Metal ComplexesThe reaction of tertiary phosphines PR3 [PR3 = P(C4H9)3, P(C2H5)2C6H5, P(i-C3H7)3] with pentacarbonyl(methoxymethylcarbene)metal complexes of chromium(O) and tungsten(O), (CO)5Cr[C(OCH3)] and (CO)5W[C(OCH3)], at low temperatures results in a reversible addition of the phosphine to the carbene ligand. The addition-dissociation-equilibrium constants depend on the temperature, the solvent, the phosphine, and the central metal.
    Notes: Bei der Umsetzung von tertiären phosphinen PR3 [PR3 = P(C4H9)3. P(C2H5)2 C6H5. P(i-C3H7)3] mit Pentacarbonyl(methoxymethylcarben)chrom(O) bzw. -wolfram(O). (CO)5Cr[C(OCH3)CH3] bzw. (CO)5W[C(OCH3)CH3], bei tiefen Temperaturen erfolgt eine Gleichgewichtskonstanten hängen von der Temperatur, dem Lösungsmittel, der Art des Phosphins und des Zentralmetalls ab.
