Abstract
Chloroalkylthiolcarbamate compounds of the formula: ##STR1## wherein Z represents ##STR2## and when Z is ##STR3## n is an integer of 4 to 10, whereas when Z is ##STR4## n is an integer of 3 to 10. These compounds are useful as effective herbicides having no harmful effect on the ecosystem, particularly extremely low toxicity to fish, and can be obtained, for example, by reacting the corresponding thiolcarbamate derivatives with a chloroalkyl halide.

A compound represented by the formula ##STR42## wherein Z represents ##STR43## and when Z is ##STR44## n is an integer of 4 to 10, whereas when Z is ##STR45## n is an integer of 3 to 10.
S-(4-chlorobutyl)-3,6-dimethyl-hexahydro-1H-azepine-1-carbothioate.
S-(3-chloropropyl)-3,6-dimethyl-hexahydro-1H-azepine-1-carbothioate.
S-(4-chlorobutyl)-(2-methyl)-piperidine-1-carbothioate.
A herbicidal composition which comprises as an active ingredient a herbicidally effective amount of a compound represented by the formula ##STR46## wherein Z represents ##STR47## and when Z is ##STR48## n is an integer of 4 to 10, whereas when Z is ##STR49## n is an integer of 3 to 10 and an agriculturally acceptable carrier.
