<p>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-¢(phos-phinyl)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.</p> |
