In 1964, slender-spikerush was received major attention as weeds in paddy field because of revelation resistance to the effect of herbicide hithertofore in use.
Authors aimed at search of herbicide for controlling slender-spikerush.
A large number of compounds have synthesized, laying stress on S-benzyl thiolcarbamates.
These compounds were evaluated for especially slender-spikerush in addition to barnyard grass and broad leaf plant as usual.
From the results, S-4-chlorobenzyl N, N-diethylthiolcarbamate (Benthiocarb) was selected as a compound having most effectiveness.
On the other hand, the preparation process of carbonyl sulfide was established and has been applied to the synthesis of Benthiocarb.
By this process, Benthiocarb was obtained with high-purity and high-yield.
