Benzenesulfonamide compounds potentiate 2,4-D induced embryogenesis in plants. In particular, 4-chloro-N-methyl-N-(2-methylphenyl)benzenesulfonamide and analogs induce somatic embryogenesis in plants. Methods of inducing somatic embryogenesis comprise exposing selected plant tissues, e.g. seed embryos, to auxins, e.g. 2.4-D and the benzenesulfonamide compounds. Compounds can be prepared by reacting sulfonyl chloride, an amine and pyridine in CH
