Reactions of selenium with imines (RR1CNR2) 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 (RR1CHSe)2 in good to excellent yields. The proposed mechanism suggests that both in situ generated carbonyl selenide (SeCO) and hydrogen selenide (H2Se) are involved in the reaction.
硒与一氧化碳,水和三乙胺存在下的亚胺和亚胺的亚胺(RR 1 CNR 2)反应在需氧处理中导致还原性硒化,得到对称的硒化物(RR 1 CHSe)2,优良至极好产量。所提出的机理表明,原位生成的羰基硒化物(SeCO)和硒化氢(H 2 Se)均参与了反应。
