Thiocarbamic 0-aryl esters

Carbamate compounds are usually subdivided into at least three main groups with respect to their structure and general use (see Figure 1) insecticides, herbicides, and thio- or dithiocarbamates. A variety of R groups may be substituted in the molecule producing, as is the case for insecticides, a variety of alkyl or aryl esters of carbamic acid. Although technically characterized as carbamate pesticides, thio- and di-thiocarbamate fungicides are not included in this... 

Aryl TV-substituted thiocarbamates 787 An 0-aryl chlorothioformate (1 mole) is dropped slowly into a solution of an amine (2 moles) in acetone or ethanol at 20-30°, with stirring. After a further hour s stirring, the mixture is poured into water, and the precipitated ester is collected, dried, and recrystallized from ethanol.
