    摘要: Substituted 2,3-dihydrobenzofurylmethyl esters of the formula I ##STR1## where R.sup.8 is hydrogen or alkyl of up to 5 carbon atoms, R.sup.9 is alkyl, haloalkenyl or haloalkynyl, each of up to 5 carbon atoms,R.sup.10 is halogen or alkyl of up to 5 carbon atoms,R.sup.11 is halogen or alkyl of up to 5 carbon atoms, A is halogen, alkyl, alkoxy, trihaloalkyl or trihaloalkoxy, each of up to 5 carbon atoms, cyano or nitro,B is alkyl, alkenyl or alkynyl, each of up to 4 carbon atoms, or an alicyclic radical of 3 to 7 carbon atoms and n is from 0 to 3,R.sup.2 is hydrogen, cyano or alkyl, alkenyl or alkynyl, each of up to 5 carbon atoms, andR.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are identical or different and each is hydrogen, halogen or alkyl, alkenyl, alkynyl or alkoxy, each of up to 5 carbon atoms, and R.sup.9 may also be alkenyl of up to 5 carbon atoms if R.sup.2 is cyano or is alkyl, alkenyl or alkynyl, each of up to 5 carbon atoms.The novel compounds are useful in pest control.
