title: [Phytotoxic activity of triazene derivatives. VI. 1-aryl-3-arylalkyl-3-alkyltriazene derivatives].
abstract: A series of of 1-aryl-3-arylalkyl-3-alkyltriazenes (B) was prepared and studied for phytotoxic activity. The previously unknown substances [Table I: substances (I leads to XVI)] were prepared by condensation of the appropriate diazonium salt with the required secondary amine in an alkaline medium and were tested against five representative plant species in both pre- and post-emergence tests at a dose of 6 kg/ha. All the substances studied were inactive in pre-emergence tests. However most of the compounds showed phytotoxic activity by absorption through the foliage. This activity was not very pronounced and always lower than triazene analogs previously studied (type A compounds) which have no aralkyl residue on nitrogen 3.
