Substituted alkynyl phenoxy compounds and their uses

摘要

An alkynyl phenoxy compound of Formula (I) is described, wherein R 1 and R 2 , similar or different, are (C 1 -C 4 )alkyl or R 1 O- and R 2 O- together represent a group -O-CH 2 -O-, -O-CH(CH 3 )-O-, -O-CH 2 -CH 2 -O-, -O-CH 2 -CH 2 -, R 3 is (C 1 -C 6 )alkyl, (C 3 -C 6 )alkenyl or -B-(CH 2 -CH 2 -O)z-R 6 where B is -CH 2 -O- or -O-, z is 0, 1 or 2 and R 6 is (C 1 -C 4 )alkyl; R 4 is hydrogen or methyl;R 5 is hydrogen or methyl;x is an integer from 1 to 2; y is 0,1 or 2; with the proviso that when R 3 is -B-(CH 2 -CH 2 -O) 2 -R 6 , y is 1 and 5-(propargyloxy)-benzo[1,3]dioxole is excluded. A pesticide composition comprising the compound of the invention and a pesticidal active ingredient is also described.
