Embodiment 1

[0028] Example 1: Compound CH 3 NH 2 Cu(HCOO) 3 Preparation: Add formic acid (2mmol), copper acetate (1mmol) and 200mmol DMF in sequence in a 25mL clean reaction kettle, stir vigorously for 30min, heat and react at 110°C for 36h, cool and filter to obtain block single crystal. The yield is about 76%.

Embodiment 2

[0029] Example 2: Compound CH 3 NH 2 Cu(HCOO) 3 Preparation: Add formic acid (1mmol), copper acetate (1mmol) and 300mmol DMF in sequence in a 25mL clean reaction kettle, stir vigorously for 30min, heat and react at 110°C for 36h, cool and filter to obtain block single crystal. The yield is about 53%.

Embodiment 3

[0030] Example 3: Compound CH 3 NH 2 Cu(HCOO) 3 Preparation: Add formic acid (2mmol), copper acetate (1mmol) and 300mmol DMF in sequence in a 25mL clean reaction kettle, stir vigorously for 30min, heat and react at 110°C for 48h, cool and filter to obtain block single crystal. The yield is about 74%.

Reaction process of the preparation method of the copper formate catalyst is simple.

Description

technical field [0001] The invention belongs to the technical field of catalyst material preparation, and relates to the preparation technology of copper formate catalyst, which lays the foundation for its catalytic application. technical background [0002] Copper-coordinated metal materials are organic-inorganic hybrid materials with one-dimensional, two-dimensional, and three-dimensional structures that are self-assembled by organic ligands and metallic copper atoms through covalent bonds. After organic molecules react with coordinated metallic copper, It will interact with the active site copper, so that the coordination metal copper ion has a wide range of applications in the field of catalysis. Therefore, the copper complex has great potential as an environment-friendly heterogeneous catalyst in the fields of organic synthetic chemistry, chemical industry, energy and environment. [0003] Benzophenone compound is a very important fine chemical intermediate, which is w...
