The reactive (ar)aliphatic thioketones 3a-c are generated by cycloreversion of the anions 2 of 1,3-dithiolane-4,5-dicarboxylates 1 and are trapped by mesitonitrile oxide (5) in a 1,3-dipolar cycloaddition to give 7.From the fragmentation of anions 12 of 1,3-dithiolane 1,1-dioxides 11, thiobenzophenone (3d) and thiocamphor (3e) are isolated, wheras thioketones 3a,c with α-hydrogen are deprotonated in situ to provide enethiolates 13.Anions 13 add nitrile oxide 5 to yield thiohydroximates 8.
