| titleOfInvention | New substituted phenyl phenyldithiocarbamates and process for the preparation thereof |
| abstract | The invention comprises substituted phenyl phenyl dithiocarbamates (or substituted phenyl phenyl amino-dithioformates) conforming to the formula <FORM:0760432/IV(b)/1> where X and X1 are the same or different and each represents a halogen atom or an alkoxy or substituted alkoxy, alkylthio or substituted alkylthio or dialkylamino group and the substituted phenyl radicals may be further substituted. A process for the production of dithio carbamates comprises the interaction of a substituted phenyl isothiocyanate of the formula X-C6H4-NCS and a thiophenol of the formula X1-C6H4-SH, X and X1 being defined as above. In examples, the 4-ethoxyphenyl 41 - ethoxyphenyldithiocarbamate is obtained by reacting 4-ethoxyphenyl isothiocyanate with 4-ethoxy-thiophenol (I); 4-n-butoxyphenyl 41-n-butoxyphenyl dithiocarbamate is obtained by reacting 4-n-butoxyphenyl isothiocyanate with 4-n-butoxythiophenol (II); 4 - n - butoxyphenyl 41-dimethylaminophenyl-dithiocarbamate is obtained by reacting 4-n-butoxythiophenol with 4-dimethylaminophenyl isothiocyanate (III); 4-chlorophenyl 41-chlorophenyl dithiocarbamate is obtained by reacting 4-chlorothiophenol with 4-chlorophenyl isothiocyanate (IV); 4-dimethylaminophenyl 41-dimethylaminophenyldithiocarbamate is obtained by reacting 4-dimethylamino thiophenol with 4 - dimethylaminophenyl isothiocyanate (V); 2 : 4 - dichlorophenyl 21 : 41 - dichlorophenyl dithiocarbamic acid is obtained by reacting 2 : 4 - dichlorothiophenol with 2 : 4 - dichlorophenyl isothiocyanate (VI); 4-(21-ethoxyethoxy) phenyl 41-(211-ethoxyethoxy) phenyl dithiocarbamate is obtained by reacting 4-(21-ethoxyethoxy) thiophenol with 4-(21-ethoxy-ethoxy) phenyl isothiocyanate (VII); and 4-ethyl thiophenyl 41-ethylthiophenyl dithiocarbamate is obtained by reacting 4-ethyl thiophenol with 4-ethylthiophenyl isothiocyanate (VIII); and comparable products are obtained using a thiophenol substituted in the 4-position by a hydroxyalkylthio, alkoxyalkylthio or alkylthioalkylthio group in the latter process. Isothiocyanate starting materials are obtained in examples from the corresponding ammonium dithio-carbamates by desulphurizing with lead nitrate (II) or by reaction with phosgene (VII; VIII). Thiophenol starting materials are obtained in examples by reduction of 4-butoxyphenylsulphonyl chloride with zinc (II) and from the corresponding anilines by the xanthate method (VII; VIII). |
