Synthesis and Biological Activity of O-Substituted aryl-O-methyl-O-propargyl Thiophosphates
Abstract:
Sixteen O-substituted aryl-O-methyl-O-propargyl thiophosphates were synthesized via tandem reaction in dichloromethane by PTC in the presence of triethyl ammonium chloride (TEBAC) and/or tetrabutyl ammonium bromide(TBAB) and triethylene diamine. At condition of m(TEBAC):m(TBAB)=1:1, pH=9~10, 25~35℃, 2.5~3 h thiophosphates were obtained in yields of 60%~97%. The structures of the compounds were characterized by elemental analysis, IR and 1H NMR spectroscopy. The compound Ⅲ5(O-4 nitrophenyl-O-methyl-O-propargyl thiophosphate) showed an excellent insecticidal activity against aphid nearly 100% in dosage of 0.025%.
