Abstract

Liquid phase oxidation of tetralin with clean air were carried out utilizing complexes composed of various heterocyclic base and CrO$_3$ in N,N-dialkylamides. In the CrO$_3$-N,N-dialkylacetamide complex catalyzed oxidations of tetralin at 90$^{\circ}$C, the maximum conversion of tetralin to the products and selectivity of ${\alpha}$-tetralone were 35.2% and 96.1%, respectively. Under this condition, however, negligible amount of ${\alpha}$-tetralol was determined.

Tetralin의 액상 공기 산화반응에 N,N-dialkylamide 용매하에서 Cr(Ⅵ)의 heterocyclic base염들과 CrO$_3$-N,N-dialkylamide complex계를 적용한 결과 CrO$_3$-N,N-dialkylamide complex의 경우, 반응온도 90$^{\circ}$C에서 tetralin의 전환율이 35.2%이었고, ${\alpha}$-tetralone의 선택율은 96.1%이었으며, ${\alpha}$-tetralol은 무시할만한 양으로 생성되었다.
