PNN LIGAND-METAL COMPLEX CATALYST, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF

摘要

A PNN ligand-metal complex catalyst, a preparation method therefor and an application thereof are disclosed. The catalyst is a compound represented by the following general formula: AA or BB, wherein: M is iron or cobalt, R is a C1-C30 alkyl or a C6-C30 aryl; R1, R2, R3, R4, R5, R6, and R7 are independently selected from a hydrogen atom, a halogen atom, a C1-C30 hydrocarbyl, a C1-C30 oxygen-containing group, a C1-C30 sulfur-containing group, a C1-C30 nitrogen-containing group, a C1-C30 phosphorus-containing group, a C1-C30 silicon-containing group or other inert functional group; and X is a halogen atom or a C1-C30 alkyl. The catalyst is prepared by performing a coordination reaction of the PNN ligand and MX2 or Py2MX2. The PNN ligand-metal complex provided in the present invention allows for excellent catalysis in the hydroboration reaction of a mono-olefin.
