描述了该小组在烯烃和炔烃的催化碳-杂原子键形成反应方面的最新进展。在C-O键形成反应中,一种定义良好的双官能团Ru-amido催化剂被成功地用于醇与丙烯酸酯的共轭加成反应。Ru-氢化物络合物(PCy3)2(CO)RuHCl是区域选择性的烯烃到羧酸偶联反应的高效催化剂,得到了合成有用的烯醇酯产品。(PCy3)2(CO)RuHCl/HBF4·OEt2原位合成的阳离子Ru-HdH催化剂被成功地用于烯烃的氢胺化反应和相关的C-N键形成反应。对于C-Si键的形成反应,在定义良好的Ru-HdH催化剂上,烯烃的区域和立体选择性脱硅化以及炔烃的硅氢化反应已经被开发出来。讨论了这些碳-杂原子成键反应的范围和机理。
The group’s recent advances in catalytic carbon-to-heteroatom bond forming reactions of alkenes and alkynes are described. For the C–O bond formation reaction, a well-defined bifunctional ruthenium-amido catalyst has been successfully employed for the conjugate addition of alcohols to acrylic compounds. The ruthenium-hydride complex (PCy3)2(CO)RuHCl was found to be a highly effective catalyst for the regioselective alkyne-to-carboxylic acid coupling reaction in yielding synthetically useful enol ester products. Cationic ruthenium-hydride catalyst generated in-situ from (PCy3)2(CO)RuHCl/HBF4·OEt2 was successfully utilized for both the hydroamination and related C–N bond forming reactions of alkenes. For the C–Si bond formation reaction, regio- and stereoselective dehydrosilylation of alkenes and hydrosilylation of alkynes have been developed by using a well-defined ruthenium-hydride catalyst. Scope and mechanistic aspects of these carbon-to-heteroatom bond-forming reactions are discussed.
