摘要: New phosphoric acid derivatives and pesticides containing these phosphoric acid derivatives as active ingredients. The new active ingredients are obtained by reaction of .alpha.-formylalkylphosphonic acid esters with phosphoric (phosphonic) acid ester halides or by reaction of .alpha.-formyl-.alpha.-haloalkylphosphonic acid esters with phosphites.The compounds are suitable for combatting pests from the classes of insects, Arachnida and nematodes in the crop protection, hygiene, stores protection and veterinary sectors.

摘要: .alpha.-Formylethane-phosphonic acid esters are manufactured by reacting vinylphosphonic acid esters with carbon monoxide and hydrogen in the presence of conventional rhodium-containing hydroformylation catalysts. The reaction is carried out at from 50.degree. to 180.degree. C. and at pressures from 20 to 1,500 bars. The products are intermediates for the synthesis of insecticidally active phosphoric acid ester derivatives.
