Beschreibung
Zusammenfassung:	The present invention refers to complexes prepared by reacting rhodium trinitrate with a suitable hydrazine and a suitable tertiary phosphine, more specifically to the compounds di(.mu.-hydrazine-N1:N2)-bis¢bis( riphenylpnosphine)rhodium (I) !dinitrate and .mu.-3-carbopentazane-N1,N4:N2,N5-bis¢bis(tri-phenylphosphine)rhodium (I) !dinitrate, which are homogenous hydrogenation catalysts and their application in the hydrogenation of the exocyclic methylene group of acid addition salts of 6-demethyl-6-deoxy-6-methylene-5-hydroxytetracycline (methacycline) to prepare a-6-deoxy-5-hydroxy-tetra-cycline (doxycycline).
