描述
应用 | Diethoxyacetonitrile may be used in the preparation of methyl 5-diethoxymethylimidazole-4-carboxylate, via anionic cycloaddition reaction with methyl isocyanoacetate |
产品介绍 | a chemical used for synthesis. With this chemical you can synthesize methyl 5-diethoxymethylimidazole-4-carboxylate by anionic cycloaddition of methyl isocyanoacetate to diethoxyacetonitrile. You can also synthesize ketoacetal, by Houben-Hoesch reaction of diethoxyacetonitrile with 1,2,4-trimethoxybenzene. Diethoxyacetonitrile is a 2,2-dialkoxyalkanenitrile derivative. Reaction of hydrocyanic acid with various ortho esters of aliphatic and aromatic acids in the presence of acidic catalyst has been reported to afford diethoxyacetonitrile. Houben-Hoesch reaction of diethoxyacetonitrile with 1,2,4-trimethoxybenzene affords tris(2,4,5-trimethoxyphenyl)methane |
