Seventy‐three α‐substituted 3‐phenoxybenzyl esters were synthesised, mostly using one of two general routes, based on the Grignard and related reactions. Esters with simpler (smaller and more polar) α‐substituents were generally more insecticidally active; correlations based on substituent volume and substituent polarity parameters were about equally significant.
