6-dipivaloyl-1,2,4,5-tetramethylbenzene were prepared by the Friedel-Grafts dipropionylation of the corresponding polymethylbenzenes, followed by the exhaustive methylation of the resulting diketones with potassium t-butoxide and methyl iodide in boiling benzene-t-butyl alcohol. The PMR and IR spectra are reported for these new compounds.
2,4-二新戊酰基-1,3,5-三甲基苯、4,6-二新戊酰基-1,2,3,5-四甲基苯和 3,6-二新戊酰基-1,2,4,5-四甲基苯的制备方法如下:相应的多甲基苯的 Friedel-Grafts 二丙酰化,然后在沸腾的苯 - 叔丁醇中用叔丁醇钾和甲基碘彻底甲基化得到的二酮。报告了这些新化合物的 PMR 和 IR 光谱。
