Pesticidal compounds have the formula: ##STR1## wherein D represents hydrogen or a cyano group X represents chlorine or bromine A represents an alkyl group n is 0 or an integer of 1-4 and RCOO is the residue of an acid RCOOH whose .alpha.-cyano-3-phenoxybenzyl ester has pesticidal properties. They are prepared by esterification methods.
Novel esters of the formula ##STR1## wherein R is selected from the group consisting of ##STR2## W is selected from the group consisting of hydrogen and --CN, Z is selected from the group consisting of --CH.sub.2 -- and --O--, and is attached to a carbon atom included between a nitrogen and the sulfur atom of Y and Y is selected from the group consisting of thiazolyl or thiadiazolyl connected to ##STR3## at one of its available positions.
