RHODIUM-CONTAINING HYDROGENATION CATALYSTS |
| 摘要 |
<p>The present invention refers to the compounds ( mu -hydrazine-N<1>:N<2>)-bis[bis(triphenylphosphine)-chlororhodium (I)] and di( mu -hydrazine-N<1>:N<2>)-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).</p> |
