Abstract

The present invention refers to the compounds (.mu.-hydrazine-N1:N2)-bis¢bis(triphenylphosphine)-chlororhodium (I)! and di(.mu.-hydrazine-N1:N2)-bis¢bis(triphenylphosphine)rhodium (I)! dichloride, 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 .alpha.-6-deoxy-5-hydroxytetracycline (doxycycline).
