The important role of [1,1′-Binaphthalene]-2,2′-diol

With the complex challenges of chemical substances, we look forward to future research findings about [1,1′-Binaphthalene]-2,2′-diol

Name is [1,1′-Binaphthalene]-2,2′-diol, as a common heterocyclic compound, it belongs to chiral-catalyst compound, and cas is 602-09-5, its synthesis route is as follows.,602-09-5

A 300mL eggplant-shaped flask, the raw material 1,1′-bi-2-naphthol (5.4g, 19mmol), Zeolyst Co. weighed Zeolith the CBV780 (2.5g), was suspended was added o- dichlorobenzene (30mL). After the suspension was heated to reflux 18 hours, heating was filtered, washed with toluene column. After concentrating the filtrate to approximately o- dichlorobenzene are others, was precipitated by adding methanol. The resultant solid was filtered to give the intermediate 7 as a white powder (4.6g, 18mmol, 90%). It was identified as the desired compound by FDMS (field desorption mass analysis).

With the complex challenges of chemical substances, we look forward to future research findings about [1,1′-Binaphthalene]-2,2′-diol
