  • Synthesis and Application of Tetraphosphane Ligands in Rhodium-Catalyzed Hydroformylation of Terminal Olefins: High Regioselectivity at High Temperature
    作者:Shichao Yu、Xiaowei Zhang、Yongjun Yan、Chaoxian Cai、Liyan Dai、Xumu Zhang
    DOI:10.1002/chem.200903109
    日期:2010.4.26
    A new class of substituted tetraphosphane ligands has been developed and applied in the rhodium‐catalyzed regioselective hydroformylation of terminal olefins. The high regioselectivity (linear selectivity is above 97 % for 1‐octene and 1‐hexene) at high temperature (140 °C) shown by these tetraphosphane ligands is remarkable considering the low regioselectivity commonly observed under similar reaction
    已经开发出一类新型的取代四膦配体,并将其应用于铑催化的末端烯烃的区域选择性加氢甲酰化反应。考虑到在使用其他双膦类似物的类似反应条件下通常观察到的低区域选择性,这些四膦配体在高温(140°C)下显示出较高的区域选择性(1-辛烯和1-己烯的线性选择性高于97%)。 。还研究了二芳基膦部分上取代基的空间和电子效应。

    申请人:Wuhan Catalys Technology CO., LTD
    公开号:US20190337866A1
    公开(公告)日:2019-11-07
    A homogeneous catalytic reaction method and a catalyst for isomerization and hydroformylation of long-chain internal olefins are disclosed. A rhodium-ruthenium metal complex is used as a catalyst; and the ligands are tetradentate phosphine ligands. By means of the catalytic system, homogeneous internal olefin isomerization aid hydroformylation can be performed under a certain temperature and pressure to obtain aldehyde products having high normal to iso ratios. The present invention is applicable to not only long-chain internal olefins (≥C8) but also internal olefins having a carbon number less than 8.
