摘要：

Strong catalyst effects on the O- vs. C-alkylation ratio of 1,1-dimethylindan-2-one (4) by dimethyl sulfate are found. They differ in the two consecutive alkylation steps and range between <1 and approximate to 60. No such catalyst influence exists in the methylation of 2-methylindane-1,3-dione (1).
