In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 33143-29-2, name is 2,2-Dimethyl-2H-chromene-6-carbonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. 33143-29-2
General procedure: For NaIO4/imidazole system, the reaction was carried out with alkene (1 mmol), n-nonane (internal standard, 1 mmol), NaIO4 (2 mmol) and the catalyst (5% mmol) at 25 C for 5 h in the 2:1 mixture of acetonitrile : water. The catalyst was precipitated from the reaction mixture by adding hexane (10 mL), and then the organic phase was separated and purified on a silica gel column, and then analyzed by GC. The progress of the reaction was monitored by GC to find the optimal conversion and selectivity.
The synthetic route of 33143-29-2 has been constantly updated, and we look forward to future research findings.
