    摘要: Pesticidal compounds have the formula: ##STR1## wherein D represents hydrogen or a cyano group or an ethynyl group R.sub.a represents alkylA represents an alkyl group or a halogeno or trifluoromethyl groupn is 0 or an integer of 1-4, b is 0 or 1andRCOO is the residue of an acid RCOOH whose .alpha.-cyano-3-phenoxybenzyl ester has pesticidal properties. They are prepared by esterification methods.
