Abstract
NEW MATERIAL:A 1,3-dithiol derivative shown by formula I (R is lower alkyl; R' is alkyl, aralkyl or phenyl which may contain amino; n is 0 or 1). EXAMPLE:1,3-Dithiol-2-yliden-alpha-isobutylthioacetic acid ethyl ester. USE:Having antimicrobial actions on molds on the skin, yeast fungi and plant pathogenic germs of blast and useful as a drug such as a drug for controlling Trichophyton and an agricultural chemical. PREPARATION:For example, as shown by the reaction formula, an ester shown by formula II is treated with trichloroethane and carbon disulfide to give a compound shown by formula I. The amount of carbon disulfide used is 1-15mol. based on the compound shown by formula II and the amount of trichloroethane used is preferably 1-5mol.
