Arylalkyl esters of 4-aminopicolinic acids and 6-amino-4-pyrimidinecarboxylates are herbicides for control of weeds especially those species common to rice and wheat cropping systems and in pasture management programs.

Challenging Suzuki–Miyaura cross couplings associated with novel cropprotection active ingredients from Corteva Agriscience, Arylex and Rinskor, can be performed in water using parts per million (ppm) levels of a Pd catalyst. Each coupling required a distinct set of reaction conditions to achieve maximum selectivities and chemical yields. By way of comparison, this chemistry is not only performed
