The preparation of the α-haloketones 6, 13-16, 19, and 20 is reported. 13 or its precursor, the acyloin 9, respectively, is conveniently obtained by a Seebach synthesis. - Reaction of the haloketones with tetraethylammonium thiosulfate (21) yields the Bunte salts 22-27 wich form the thioketones 28-33 on cleavage with aqueous alkali. 29 is stable as a crystalline, blue monomer in contrast with other aromatic α-thioxoketones.This ist also true for the aromatic-aliphatic derivatives 30 and 31 as well as their isomers 32 and 33 wich do not dimerize.
