NOVEL ALDEHYDES AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A novel aldehyde, 4-formylcyclohexane-1,2-dicarboxylic acid, is prepared by the reaction of 4-cyclohexene-1, 2- dicarboxylic acid with hydrogen and carbon monoxide in the presence of a hydroformylation catalyst. Products in which hydrogen of the ring is substituted by other groups, and derivatives of the carboxyl groups, may also be prepared. Useful catalysts include rhodium carbonyl complex compounds with tertiary phosphine ligands with excess of the tertiary phosphine ligands. |
