摘要

Abstract Catalytic Friedel–Crafts acylation of benzene and unactivated benzenes such as chlorobenzene and nitrobenzene have been successfully carried out using activated hematite (α-Fe 2 O 3) as a new, heterogeneous and green catalyst. Sonication of neat α-Fe 2 O 3 in a water bath under air atmosphere at room temperature followed by heating at 200 C, dramatically increase the activity of α-Fe 2 O 3. With the catalyst loading as low as 5.0 ...
