Highly Efficient Route to Diselenides from the Reactions of Imines and Selenium in the Presence of Carbon Monoxide and Water
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.

Design, synthesis, and biological evaluation of novel miconazole analogues containing selenium as potent antifungal agents
Herein, based on the theory of bioisosterism, a series of novel miconazole analogues containing selenium were designed, synthesized and their inhibitory effects on thirteen strains of pathogenic fungi were evaluated. It is especially encouraging that all the novel target compounds displayed significant antifungal activities against all tested strains. Furthermore, all the target compounds showed excellent
