Both polarity of the carbonyl group and steric hindrance in the vicinity of the carbonyl group strongly inﬂuence the thionation. High polarity of the carbonyl groups leads to good yields of mono- and dithioimides. On the other hand, steric hindrance strongly inhibits the replacement of the oxygen atom by sulfur. — (ORZESZKO, A.; MAURIN, J. K.; MELON-KSYTA, D.; Z. Naturforsch., B: Chem.
