The present invention is directed to a catalyst composition, comprising a Group 8 metal; and a ligand having a structure selected from the group consisting of:
1
wherein R, R′ and R″ are selected from the group consisting of H, a 1-10 carbon moiety, OR
1
, and NR
2
R
3
, wherein R
1
, R
2
, and R
3
are each individually a 1-10 carbon moiety, with the proviso that one of R, R′, or R″ is not H, and that R, R′, and R″ together do not form an adamantyl moiety; and
2
wherein L is selected from the group consisting of a 1-30 carbon moiety with a tertiary carbon bound to phosphorous The present invention is also directed to a method of forming carbon-carbon, carbon-oxygen, carbon-sulfur, and carbon-nitrogen bonds between substrates using the above catalysts.
本发明涉及一种催化剂组合物,包括第8族金属;以及具有以下结构的配体之一:1其中R、R′和R″选自H、1-10碳基、OR1和NR2R3,其中R1、R2和R3分别为1-10碳基,但R、R′或R″中的一个不是H,且R、R′和R″在一起不形成一个三环戊烷基;以及2其中L选自含有与磷相结合的三元碳的1-30碳基。本发明还涉及一种利用上述催化剂在基质之间形成碳-碳、碳-氧、碳-硫和碳-氮键的方法。
