Synthesis and Biological Activity of 3-- 2,2-Dimethyl-Cyclopropane Carboxylic Phosphorates

Fourteen novel 3-(2,2-dichlorovinyl)-2,2-dimethyl-cyclopropane carboxylic phosphorates were synthesized from the intermediate α-hydroxyl phosphorates and 3-(2,2-dichlorovinyl)-2,2-dimethyl-cyclopropane carbonyl chloride. All compounds synthesized were identified by 1H NMR, IR and MS. These compounds showed certain insecticidal activity against aphid in dosage of 25mg/L, and exhibited certain fungicidal activity at 50 mg/L.
