New syntheses of 1,2-dimethyl-, 1,2,3- and 1,2,4-trimethyl-, and 1,2,3,4-tetramethyl-naphthalenes are described. Gattermann formylations can proceed abnormally above 65° both 2,3- and 1,4-dimethylnaphthalenes affording 2,4-dimethylnaphthalene-1-carbaldehyde.
描述了1,2-二甲基-,1,2,3-和1,2,4-三甲基-和1,2,3,4-四甲基萘的新合成。Gattermann甲酰化可在65°以上异常地进行2,3和1,4-二甲基萘,得到2,4-二甲基萘-1-甲醛。
