Abstract
Abstract The compounds of the formula (I) ##STR1## in which X denotes CH 2 , O, S or NR 6 , R 1 denotes alkyl, cycloalkyl, alkenyl, (substituted) phenyl, or (substituted) naphthyl, R 2 and R 3 denote alkyl, alkenyl or phenyl, or R 2 and R 3 together denote an alkylene chain, R 4 denotes --H, --CN, --CCl 3 , --C.tbd.CH, alkyl, F, or --C(S)--NH 2 , R 5 denotes pyridyl, furyl, thienyl, phthalimidyl, di(C 1 -C 4 )alkylmaleinimidyl, thiophthalimidyl, dihydrophthalimidyl or tetrahydrophthalimidyl, which may all be substituted, or substituted phenyl, or R 4 and R 5 --together with the carbon atom bridging them--denote an optionally substituted indanyl, cyclopentenoyl or cyclopentenyl radical, with the proviso that compounds of the formula I in which R 1 denotes phenyl which is substituted in the para-position by (C 1 -C 4 )alkoxy, halogen or (C 1 -C 4 )alkyl; R 2 and R 3 denote CH 3 ; X denotes O; R 4 denotes H and R 5 denotes 3-phenoxyphenyl or (4-fluoro-3-phenoxy)phenyl being excepted, have advantageous insecticidal, acaricidal and nematocidal properties.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
350 words
A compound of the formula ##STR324## wherein X is CH 2 , O or S, Y is halogen or sulfonate, R 2 and R 3 , independently of one another, are (C 1 -C 3 )alkyl, (C 2 -C 8 )alkenyl or phenyl, R 4 is H, CN, CCl 3 , F or (C 1 -C 4 )alkyl, R 5 is a phenyl of the formula ##STR325## in which R 10 and R 11 , independently of one another are H, halogen, (C 1 -C 4 )alkyl, (C 1 -C 4 )alkoxy, (C 1 -C 4 )haloalkyl, phenyl, N-pyrrolyl; or or a group of the formula ##STR326## in which R 12 and R 13 , independently of one another are H, halogen, (C 1 -C 4 )alkyl, (C 1 -C 4 )alkoxy or (C 1 -C 4 )haloalkyl, U being CH 2 , CO, O or S, V and W being CH or N, however, when either V or W is N, the other is CH, p and q, independent of one another are integers from 0 to 5, but with the condition that the sum of p+q is an integer from 1 to 5, r and s, independent of one another, are 0, 1 or 2, with the condition that the sum of r+s is 0, 1 or 2 and with the further condition that, if either R 10 or R 11 is a group corresponding to formula (D), p and q must be 0 or 1 and p+q must be 1 or 2; or R 5 is a pyridyl group of the formula ##STR327## in which R 14 is H, halogen other than I, (C 1 -C 4 )alkyl, (C 1 -C 4 )alkoxy or (C 1 -C 4 )haloalkyl, and Hal is halogen or H; or R 5 is a thienyl or furyl of the formula ##STR328## in which Z is O or S, R 15 is H, halogen, (C 1 -C 4 )alkyl, (C 1 -C 4 )alkoxy, (C 1 -C 4 )haloalkyl, CN or NO 2 , and R 16 is benzyl, propargyl or allyl.
