MICROWAVE INDUCED STEREOSELECTIVE CONVERSION OF DIALKYL 2-(IMIDO-N-YL)-3- (TRIPHENYLPHOSPHORANYLIDENE)BUTANEDIOATES TO ELECTRON-POOR (Z)-N-VINYLIMIDES IN THE PRESENCE OF IRON(II) SULFATE POWDER IN SOLVENT-FREE CONDITIONS |
Microwave was found to catalyze stereoselective conversion of dialkyl 2-(imido-N-yl)-3-(triphenylphosphoranylidene)butanedioates to electron-poor (Z)-N-vinylimides in the presence of iron(II) sulfate powder in solvent-free conditions in 4 min. |
