초록

Chloromethylation, malonic ester 합성법 및 decarboxylation에 의한 중간체들을 거친 tert.-butyl ${\beta}$-(o-tolyl)-perpropionate 치환체들의 합성을 기술하였다. 심하지 않은 치환기효과를 나타내는 bromo-, chloro- 및 methyl- 기를 가진 중간체들은 좋은 수율로 얻어져서 목적한 바 과산화 ester들을 얻었으나 nitro기를 가진 중간체는 극히 적은 수율로 얻어졌고 한편 센 electron donating effect를 나타내는 group로 치환된 toluene들의 chloromethylation은 polymerize하는 결과를 가져왔다.

The syntheses of substituted tert.-butyl ${\beta}$-(o-tolyl)- perpropionates via intermediates obtained by chloromethylation, malonic syntheses and decarboxylation is described. The intermediates substituted with a group possessing moderate substituent effect such as bromo, chloro, and methyl group were obtained in good yields. The nitro-substituted intermediat was obtained in poor yield. The chloromethylation of toluenes containing electron donating groups resulted in polymerization.
