Abstract
Hansch and Muir1 have shown that a free ortho position is required for growth regulatory activity in the phenoxyacetic acid series (Avena straight-growth test), and have suggested that the active compound reacts “with a substrate at two points, first by means of the carboxyl group, and second at a position ortho to the attachment of the carboxyl group”. This explanation does not account for Wain's finding2 that one hydrogen on the α-carbon atom was essential for activity (Went pea test).
