Tominaga, Yoshinori published the artcileSynthesis of methylthiomaleimides for the preparation of pyridazines and related compounds, COA of Formula: C12H14IN, the publication is Journal of Heterocyclic Chemistry (2002), 39(3), 571-591, database is CAplus.
New functionalized maleimides [3-(methylthio)-2,5-dioxo-1H-pyrroles] were obtained by the reaction of ketene dithioacetals with nitromethane or the reaction of nitro ketene dithioacetal with active methylene compounds in the presence of the appropriate base in DMSO followed by treatment with methanol. These maleimides reacted with various nucleophilic reagents such as electron-rich aromatic and heteroaromatic compounds like dialkylanilines, aminophenols, indoles, indolizines, and cyclazines to give the corresponding 3-aryl- or -heteroaryl-1H-pyrrole-2,5-diones. Styryl and merocyanine dyes, and polycyclic pyridazinediones as chemiluminophors and succinimides were also obtained from these maleimides with good results.
