  • Phosphorothiolate pesticidal composition
    Patent number: 4113864
    Abstract: Phosphorothiolates represented by the formula, ##STR1## wherein R is an alkyl; A is an alkyl, haloalkyl, alkenyl, alkinyl, alkylthioalkyl, phenylthioalkyl, phthalimidoalkyl or phenylalkyl; X is hydrogen, a halogen or an alkyl; and n is an integer of 1 to 5, are obtained by (1) reacting sodium or potassium hydrosulfide with a compound represented by the formula, ##STR2## WHEREIN R, X and n have the same significances as mentioned above, to prepare a thiophosphate represented by the formula, ##STR3## wherein R, X and n have the same significances as mentioned above; and M is an alkali metal, and then (2) reacting said thiophosphate with a halide represented by the formula,Y -- Awherein A has the same significance as mentioned above; and Y is a halogen.The phosphorothiolates have insecticidal and fungicidal activities.
