A series of 4,5-diamino-substituted-1,2-benzoquinones were prepared from catechol and the corresponding secondaryamines in high yield in a single step using copper complex formation to stabilize the intermediate. The cytotoxicity of the products under various conditions was evaluated using the EMT-6 mammary carcinoma cell line, and antitumor activity was tested in the L1210 murine leukemia. The 4
