Sulfinamide derivatives, a process for preparing the derivatives and

A novel S-methyl N-[{N-methyl-N-(N,N-disubstituted aminosulfenyl)carbamoyl}oxy]thioacetamidate derivative represented by the formula (I): ##STR1## which has insecticidal, miticidal or nematocidal activity comparable to or higher than known methomyl but which is quite low in toxicity to warm-blooded animals as compared to methomyl, is disclosed. An insecticidal, miticidal or nematocidal composition containing the same, and a process for preparing the same are also disclosed. A method for controlling noxious insects, mites or nematodes by using the same is further disclosed.

Carbamate derivatives, insecticidal, miticidal or nematocidal

An aminosulfenyl chloride derivative represented by the formula (I): ##STR1## wherein R.sup.1 and R.sup.2 are defined in the specification, which is useful as an intermediate for the preparation of a carbamate derivative represented by the formula (III): ##STR2## wherein R.sup.1 and R.sup.2 are the same as defined above, the carbamate derivative having an insecticidal, miticidal or nematocidal activity, is disclosed. A process for preparing the aminosulfenyl chloride of the formula (I), and a process for preparing the carbamate derivative of the formula (III) using the aminosulfenyl chloride of the formula (I) are also disclosed.

Aminosulfenyl chloride derivatives

This invention relates to carbamate derivatives represented by the formula (I): ##STR1## a process for preparing the derivatives and insecticides containing the derivatives.
