Thio compoundsQ 0590 Direct Thionation and Selenation of Amides Using Elemental Sulfur and Selenium
and Hydrochlorosilanes in the Presence of Amines. — The reaction takes place se-lectively at the amide moiety even if other carbonyl groups are present. The use of 1.1 equiv. each of sulfur or selenium, an additive and silane as a reductant is crucial. Mostly the best results are obtained with DMAP or DABCO. — (SHIBAHARA*, F.; SUGIURA, R.; MURAI, T.; Org. Lett. 11 (2009) 14, 3064-3067; Dep. Chem., Fac.
