A rhodium‐catalyzed one‐pot hydroformylation of olefins with CO2 , hydrosilane, and H2 has been developed that affords the aldehydes in good chemoselectivities at low catalyst loading. Mechanistic studies indicate that the transformation is likely to proceed through a tandem sequence of poly(methylhydrosiloxane) (PMHS) mediated CO2 reduction to CO and a conventional rhodium‐catalyzed hydroformylation
已开发出铑在CO 2 ,氢硅烷和H 2催化下的烯烃单锅加氢甲酰基化反应,可在低催化剂负载量下提供具有良好化学选择性的醛。机理研究表明,这种转化很可能是通过聚甲基丙烯酸甲酯(PMHS)介导的将CO 2还原为CO的串联序列和常规的铑催化的CO / H 2加氢甲酰化来进行的。发现氢硅烷基烷介导的CO 2还原优先于醛的还原对于在反应条件下选择性形成醛至关重要。
