Reactions of 2,3-Dichloromaleimides with Methyleneactive Compounds2,3-Dichloromaleimides 1 react with activated methylene compounds mainly under monosubstitution to give 2-6. Replacement of the second chloroatom gives 2,3-disubstituted maleimides 9-15 and stable ylides 16-27 with pyridine and triphenylphosphine, respectively. A general synthesis for such maleimid-ylides was found in a one-batch reaction from 2,3-dichloromaleimides 1 with methyleneactive compounds and pyridine or triphenylphosphine.
