Abstract

Abstract Reactions of selenium with imines (RR 1 C [DOUBLE BOND] NR 2) of aldehydes and ketones in the presence of carbon monoxide, water and triethylamine lead to reductive selenation, on aerobic work-up, to afford symmetrical diselenides (RR 1 CHSe) 2 in good to excellent yields. The proposed mechanism suggests that both in situ generated carbonyl selenide (SeCO) and hydrogen selenide (H 2 Se) are involved in the reaction.
