摘要

4, 5-Dichloroanthrone (3). A suspension of quinone!(0.56 g, 2 retool) in dioxane (10 mL) and then Na2S204• 2H20 (I, 26 g, 6 mmol) were added to a sohltion of NaOH (0, 48 g, 12 mmol) in water (50 mL) heated to 100 C. The mixture was stirred for 20 min with boiling and then cooled. The residue was separated and recrystallized from benzene.-Anthrone 3 was obtained (0.29 g, 59%), mp 196--201 C (cf Ref. 2: m.~ 198 C). tH NMR (CDCI3),~: 4.17 (s, ...
