- NEW REACTIONS OF 4,5-DICHLORO-2-DICHLOROMETHYLENE-4-CYCLOPENTENE-1,3-DIONE
-
The reaction of 4,5-dichloro-2-dichloromethylene-4-cyclopentene-1,3-dione with DMFA gives a high yield of 2,3-dichloro-5-(dimethyliminiomethyl)-2-cyclopentene-1,4-dione. 2,3-Dichloro-5,5-bismethylthio-2-cyclopentene-1,4-dione was isolated as a result of the analogous reaction with DMSO.A reaction mechanism involving diketocarbene is proposed.
