The present invention relates to the field of catalytic hydrogenation and, more particularly, to a process for the reduction by hydrogenation, using molecular H2, of a C6-C20 conjugated dienal into the corresponding deconjugated enal, characterized in that said process is carried out in the presence of a catalytic system comprising at least a base and at least one complex in the form of a rhodium complex comprising a C34-C60 bidentate diphosphine ligand (L2) coordinating the rhodium.
本发明涉及催化加氢领域,更具体地涉及一种使用分子H2对C6-C20 共轭二烯醛进行还原的过程,将其转化为相应的脱共轭烯醛。该过程的特征在于,在存在至少一种碱和至少一种以C34-C60双齿二
膦配体(
L2)配位于
铑的形式的
铑络合物的催化系统的情况下进行。
