The hydroformylation of propene to give predominantly iso‐butanal has been achieved; class‐leading selectivity is possible even at higher temperatures that deliver fast conversion. Racemic rhodium complexes of bidentate phospholane phosphites derived from tropos‐biphenols and unusual solvent systems are the key to the selectivity observed.
已经实现了丙烯的加氢甲酰化反应,主要生成异丁醛。即使在提供快速转化的更高温度下,也可以实现一流的选择性。由对位双酚和不寻常的溶剂体系衍生的亚齿二膦酸酯亚磷酸酯的外消旋铑配合物是观察到的选择性的关键。
