Hydroformylation catalyst system with syngas substitute

Described herein are hydroformylation catalyst systems and processes useful for producing aldehydes from olefin substrates without the use of carbon monoxide gas. A hydroformylation catalyst system includes: a hydroformylation catalyst complex including a Group 9 metal complexed with a phosphine-based ligand; a syngas substitute including formic acid and an anhydride compound that forms carbon monoxide in situ; and hydrogen, which may or may not be derived from the syngas substitute. The process involves reacting an olefin substrate with a synthesis gas substitute in the presence of a hydroformylation catalyst complex, where the synthesis gas substitute forms carbon monoxide and optionally hydrogen in situ, and then separating an aldehyde compound from the reaction mixture. 本文描述的是可用于在不使用一氧化碳气体的情况下从烯烃底物生产醛的加氢甲酰化催化剂体系以及方法。加氢甲酰化催化剂体系包括：加氢甲酰化催化剂络合物，其包括与基于膦的配体络合的第9族金属；包括甲酸和酸酐化合物的合成气替代物，其原位形成一氧化碳；以及氢，其可源自合成气替代物或者不源自合成气替代物。该方法涉及在加氢甲酰化催化剂络合物的存在下使烯烃底物与合成气替代物反应，其中合成气替代物原位形成一氧化碳以及任选地氢，然后从反应混合物分离醛化合物。
