Document Type and Number:
Japanese Patent JPH04364178
Kind Code:
A
Abstract:
PURPOSE: To obtain the subject compound which is synthetic intermediate of sulfur-containing organic compounds such as medicines, agricultural chemicals, etc., without using toxic carbonyl sulfide gas by treating a di-substituted dithiocarbamic acid phenacylethyl with a specific soft metal salt.
CONSTITUTION: A compound expressed by formula I (R is di-substituted amino; Ar is phenyl which may have a substituent group) is reacted with a salt of soft metal such as silver, copper (I) or mercury (II) (preferably a silver salt), preferably in an organic solvent such as alcohols in the presence of a strong acid to provide the objective compound expressed by formula II (X- is silver radical).
