Some new phosphinic acid derivatives of aminothio methylcarbamates have been synthesized and tested as pesticides. The new compounds are active against insects, mites, and nematodes. The N-[(phosphinyl)amino]thio- and N-](phosphinothioyl)amino]thio-methylcarbamates are readily prepared by the general procedure of reacting a phosphinic acid amide with sulfur dichloride so as to obtain the corresponding N-(chlorothio)phosphinic acid amide which reactant will react with a methylcarbamate so as to produce the corresponding object compounds, the N-[(phosphinyl)amino]thio- and N-[(phosphinothioyl)-amino]thio-methylcarbamates of this invention. Various formulations for pesticidal use are described along with appropriate rates of application.
