Tetralin의 액상 공기 산화반응에 N,N-dialkylamide 용매하에서 Cr(Ⅵ)의 heterocyclic base염들과 CrO3-N,N-dialkylamide complex계를 적용한 결과 CrO3-N,N-dialkylamide complex의 경우, 반응온도 90℃에서 tetralin의 전환율이 35.2%이었고, α-tetralone의 선택율은 96.1%이었으며, α-tetralol은 무시할만한 양으로 생성되었다.

Liquid phase oxidation of tetralin with clean air were carried out utilizing complexes composed of various heterocyclic base and CrO3 in N,N-dialkylamides. In the CrO3-N,N-dialkylacetamide complex catalyzed oxidations of tetralin at 90℃, the maximum conversion of tetralin to the products and selectivity of α-tetralone were 35.2% and 96.1%, respectively. Under this condition, however, negligible amount of α-tetralol was determined.
