Described herein is a hydroformylation catalyst system and method useful for producing aldehydes from olefin substrates, without using carbon monoxide gas. The hydroformylation catalyst system includes a hydroformylation catalyst complex including a Group 9 metal complexed with a phosphine-based ligand; a syngas surrogate including formic acid and an anhydride compound, which forms carbon monoxide in situ; and hydrogen, which may derived from the syngas surrogate or not derived from the syngas surrogate. The method involves reacting the olefin substrate with a syngas surrogate in the presence of a hydroformylation catalyst complex, wherein the syngas surrogate forms carbon monoxide, and optionally hydrogen, in situ, and then isolating the aldehyde product from a reaction mixture.
本文描述的是一种加氢甲酰化催化剂系统和方法,用于在不使用一氧化碳气体的情况下从烯烃底物生产醛。加氢甲酰化催化剂系统包括加氢甲酰化催化剂络合物,包括与膦基配体络合的第 9 族金属;合成气代用品,包括甲酸和酸酐化合物,可在原位形成一氧化碳;以及氢气,可来自合成气代用品或不来自合成气代用品。该方法包括在加氢甲酰化催化剂复合物存在下使烯烃底物与合成气代用品反应,其中合成气代用品在原位形成一氧化碳和氢,然后从反应混合物中分离出醛产物。
