摘要

Heteroaryl alkyl metals 3 undergo methylation and ethylation upon treatment with bistrimethylsilylperoxide la and bistriethylsilylperoxide 1b. Benzothiazolylderivatives 3c-d and 3h-j react with la giving trimethylsilyloxylation other than methylation products. The reaction of 3a-b with la leads also to the trimethylsilylation product 1. The reaction of 3g, 3c and 3k with 1b provides the ethylated derivatives 2h, 2d and 2n respectively. No reaction ...
