4-R-5-Ar-A-1,2-dithiole-3-one derivs. of formula (I) their acid addn. salts, metallic salts and addn. salts with organic bases are new. In (I) a) R = H or chloro; A = O, -NH, alkylimino, alkylcarbonylimino or formyl-imino, Ar = phenyl (opt. substd.) or Ar = pyridyl, quinolyl, isoquinolyl, indanyl or quinoxalinyl; b) R = H; A = as defined above and Ar = alkyl-substd. phenyl or c) R = chloro; A = O, alkylcarbonylimino or formylimino and Ar = alkyl-substd. phenyl. Unless otherwise defined, alkyl gps. and alkyl parts of radicals are opt. branched 1-4C.
