“…The reaction of O,O-dialkyl phosphonates with aldehydes is a convenient method used to synthesize 1-hydroxyphosphonates, which have been reported in many literatures [14][15][16]. However, there are few reports on the reaction of O-methyl methylphosphinate 1 with thiophene-2-carbaldehyde.…”

A series of novel O-methyl methyl 1-(substituted phenoxyacetoxy)-1-(thien-2-yl)methylphosphinates 5a-h were synthesized. Their structures were confirmed by IR, 1 H NMR, mass spectroscopy, and elemental analyses. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal and fungicidal activities. For example, the title compounds 5c, 5d, and 5g possess 90-100% inhibition against the tested plants at the concentration of 10 mg/L and 100 mg/L, whereas the title compounds 5a, 5b, 5c, and 5h possess 70-94% inhibition against Phyricularia grisea and Sclerotinia sclerotiorum at the concentration of 50 mg/L.

A series of O,O-dialkyl 1-(3-trifluoromethylphenoxyacetoxy)-1-substituted methylphosphonates were synthesized by the condensation of O,O-dialkyl 1-hydroxyalkylphosphonates with 3-trifluoromethylphenoxyacetyl chloride. Their herbicidal activity against a set of weed species was examined. The results showed that improvement of herbicidal activity required a reasonable combination of substituents in the parent structure, which provided some hints for further study of structure modification. ©Pesticide Science Society of Japan

“…O,O-Dimethyl 1-hydroxyalkylphosphonate or O,O-diethyl 1-hydroxyalkylphosphonate 4 could be prepared by the reaction of dimethyl phosphite or diethyl phosphite 3 and several kinds of aldehydes using potassium fluoride and alumina (mass ratio was 1:1) as catalyst in yield of 65-94% according to literatures [14,15].…”
