Embodiment 1
[0030] A ferrocene-containing carbamate compound, chemical formula:
[0031] .
[0032] (1) Synthesis of ferrocene formaldehyde: under nitrogen protection, cooling in an ice bath, 14.6g (0.2 mol) of dimethylformamide in a constant pressure funnel was dropped into 18.6g (0.1 mol) of ferrocene in 10 minutes. 75 mL of dry chloroform solution; then, 30.6g (0.2 mol) of phosphorus oxychloride was dropped into the reaction bottle within half an hour, after the addition was completed, the oil bath was heated to 55°C, heated and stirred for 20hrs, and the temperature of the oil bath was kept constant Lower than 60°C; after the reaction is completed, pour the reaction mixture into ice water, most of the solids in it are unreacted ferrocene, filter out the solid insoluble matter by suction filtration, carefully neutralize the filtrate with sodium carbonate powder, and then extract it with circulation The device repeatedly extracted the reaction mixture several times, all the extracts ...
Embodiment 2
[0037] (1) Synthesis of ferrocene formaldehyde: Under the protection of nitrogen, cool in an ice bath, drop 14.6g (0.2 mol) dimethylformamide into 18.6g (0.1 mol) ferrocene in a constant pressure funnel within 10 minutes 75 mL of dry chloroform solution; then, 30.6g (0.2 mol) of phosphorus oxychloride was dropped into the reaction flask within half an hour, after the addition was completed, the oil bath was heated to 60°C, and heated and stirred for 20hrs to bring the temperature of the oil bath to Always lower than 60°C; after the reaction is completed, pour the reaction mixture into ice water, the solids in which are mostly unreacted ferrocene, filter the solid insolubles by suction filtration, carefully neutralize the filtrate with sodium bicarbonate powder, and then use The reaction mixture was repeatedly extracted by a circulating extraction device, all the extracts were combined, washed with water, the organic layer was dried with anhydrous sodium carbonate, and the solve...
Embodiment 3
[0042] (1) Synthesis of ferrocene formaldehyde: under the protection of helium, cool in an ice bath, drop 18.6g (0.1 mol) of ferrocene into 14.6g (0.2 mol) DMF dimethylformamide in a constant pressure funnel within 10 minutes Iron in 75 mL of dry chloroform solution; then, 30.6g (0.2 mol) of phosphorus oxychloride was dropped into the reaction flask within half an hour, after the dropwise addition was completed, the oil bath was heated to 60°C, heated and stirred for 20 hours, and the oil bath The temperature is always lower than 60°C; the reaction is completed, the reaction mixture is poured into ice water, the solids in which are mostly unreacted ferrocene, the solid insolubles are filtered by suction filtration, the filtrate is carefully neutralized with magnesium carbonate powder, and then used The reaction mixture was repeatedly extracted by a circulating extraction device, all the extracts were combined, washed with water, the organic layer was dried with anhydrous sodium...
