摘要

The indirect electrooxidation of ketones in ammoniacal methanol using iodide ion as a mediator afforded 2, 2-dialkyl-2, 5-dihydro-IH-imidazoles 3 via an oxidative cyclocoupling of ketimine intermediates formed from ketones and ammonia. The treatment of 3 with dilute HC1 gave a-amino ketone hydrochlorides 4 and the parent ketones in good yields. A similar electrooxidation of 3 resulted in the formation of the corresponding W-imidazoles 6, which ...
