A strategy for the direct functionalization strategy of inertial dialkyl phosphonates with hydroxy compounds to afford diverse mixed phosphonates with good yields and functional-group tolerance has been developed. Mechanistic investigations involving both NMR studies and DFT studies suggest that an unprecedented highly reactive PV species (phosphoryl pyridin-1-ium salt), a key intermediate for this new synthetic transformation, is generated in situ from dialkyl phosphonate in the presence of Tf2O/pyridine.

Synergistic arthropodicidal compositions containing (1) a phosphorus-containing compound of the formula STR1 in which R1, R2 and R3 each independently is an optionally substituted alkyl, alkenyl or aryl radical, at least one of R1, R2 and R3 being an optionally substituted alkenyl radical unsaturated in the 2-position, X is oxygen or sulphur, and Y and Z each independently is oxygen, sulphur or a direct bond; and if both Y and Z are oxygen or sulphur or a direct bond, then any of R1, R2 and R3 can denote propargyl in addition to the radicals indicated above, and (2) at least one (A) carbamate, (B) carboxylic acid ester, (C) phosphoric acid ester other than (1), (D) halogenocycloalkane or (E) halogenoalkane.
