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.

It was shown that perchloro-2-cyclopenten-1-one, perchloro-2-cyclopentene-1,4-dione, perchloro-2,5-dihydrofuran-2-one, perchloroindenone, and 2,3,4,4,5-pentachloro-2-cyclopenten-1-one enter into the Pummerer reaction with dimethyl sulfoxide like acid chlorides.
