摘要

我们制备了具有自组装 6-吡啶酮结构的新型膦，对其进行了表征，并在多种烯烃的加氢甲酰化过程中对其进行了检验。在工业相关条件下，在[Rh(acac)(CO)2]存在下对各种已知和新型配体进行了测试，结果表明 6,6'-(苯基膦二基)双(吡啶-2(1H)-酮)（DPONP）对 1-辛烯的加氢甲酰化效果最好。对照实验和建模研究表明，这种配体在较高温度下（>100 °C）会发生二聚反应。最佳催化剂体系能够在工业应用温度下，以较低的配体负载量保持较高的产品线性度（大于 90%），适用于多种烯烃。

Highly (regio)selective hydroformylation of olefins using self-assembling phosphines†

New phosphines with self-assembling 6-pyridinone moities were prepared, characterized, and examined in the hydroformylation of diverse olefins. Testing various known and novel ligands in the presence of [Rh(acac)(CO)₂] under industrially relevant conditions, the hydroformylation of 1-octene proceeds best with 6,6′-(phenylphosphanediyl)bis(pyridin-2(1H)-one) (DPONP). Control experiments and modelling studies indicate dimerization of this ligand at higher temperatures (>100 °C). The optimal catalyst system is able to conserve high product linearity (>90%) for a broad range of olefins at industrially-employed temperatures at low ligand loading.
