Ortho-pyrimidyl-phosphoramide esters as insecti- and acaricides - from phos-phoramide chlorides and 6-hydroxy-pyrimidine salts

摘要

Cpds of the formula (I): where R1 and R2 are (1-4C) alkyl, and Y is O or CH2 are also used as ovicides. They have a low phytotoxicity and a low toxicity to warm blooded animals. (I) are prepd. from a cpd. R1O(R2HNO) P(=O)X(where X is halogen) and the correspondingly suitable 6-hydroxy -pyrimidine salt.
