  选择性酯加氢的工程催化剂

  摘要：

  当前需要开发有效的催化剂和用于合成官能化的（烯烃和/或手性的）伯醇和氟代半缩醛的方法。这些是制药，农用化学品，香水等的有价值的构建基块。从经济角度看，板凳稳定的高砂国际机场。Corp.的Ru-PNP（通常称为Ru-MACHO）和Gusev的Ru-SNS络合物可以说是最吸引人的从酯和H 2中获取伯醇的分子催化剂（Waser，M.et al.Org.Proc。 RES。开发。2018，22， 862）。这项工作介绍了具有经济竞争力的Ru-SNP（O）z络合物（z= 0，1），它们结合了这两种催化剂的关键结构要素。特别地，发现将SNP杂原子结合到配体骨架中对于在动力学控制条件下合成氟半缩醛中设计更具产物选择性的催化剂至关重要。基于实验观察和计算分析，本文进一步扩展了对KO- t -C 4 H 9在酯加氢中的促进作用的最新认识。它试图解释为什么从大约25 mol％的碱开始出现最大的转化率，而以酮为底物的情况只有10

  The present invention relates generally to novel achiral and chiral sulfur-, nitrogen- and phosphorus-containing ligands, designated as NNS-type, P(0)NS-type, PNS-type, SNNS-type, SNNP(0)-type, or SNNP-type polydentate ligands and transition metal complexes of these ligands. The catalysts derived from these ligands and transition metal complexes may be used in a wide range of catalytic reactions, including hydrogenation and transfer hydrogenation of unsaturated organic compounds, dehydrogenation of alcohols and boranes, various dehydrogenative couplings, and other catalytic transformations.

  本发明涉及新型的无手性和手性硫、氮和磷含配体，被称为NNS型、P(0)NS型、PNS型、SNNS型、SNNP(0)型或SNNP型多齿配体以及这些配体的过渡金属配合物。从这些配体和过渡金属配合物衍生的催化剂可用于各种催化反应，包括不饱和有机化合物的加氢和转移加氢、醇和硼烷的脱氢、各种脱氢偶联反应以及其他催化转化。
