Abstract
A composition of matter is described herein which has insecticidal activity and methods of use. The insecticide composition is defined by the following formula: ##STR1## in which R and R.sub.1 are independently selected from the group consisting of hydrogen, 2-halogen, 4-halogen, and 2,6-dihalogen. An additional composition of matter is described herein which is useful as an intermediate in the manufacture of the insecticide composition described above. The intermediate composition is defined by the following formula, in which R is as described above: ##STR2##
Claims35
A compound having the formula ##STR14## in which R and R.sub.1 are independently selected from the group consisting of hydrogen, 2-halogen, 4-halogen, and 2,6-dihalogen.
A method of controlling insects comprising applying to the habitat thereof an insecticidally effective amount of a compound having the formula ##STR15## in which R and R.sub.1 are independently selected from the group consisting of hydrogen, 2-halogen, 4-halogen, and 2,6-dihalogen.
A compound having the formula ##STR16## in which R is selected from the group consisting of hydrogen, 2-halogen, 4-halogen, and 2,6-dihalogen.
A process for the manufacture of a compound having the formula ##STR17## wherein R and R.sub.1 are independently selected from the group consisting of hydrogen, 2-halogen, 4-halogen, and 2,6-dihalogen comprising
- a. reacting a compound having the formula ##STR18## wherein R is defined above with diethyl chlorophosphite and a suitable organic base to produce a compound having the formula ##STR19## and b. reacting the product of step (a) with a compound having the formula ##STR20## wherein R.sub.1 is defined above to produce the end product.
