Studies on Herbicides and Plant Growth Regulators

Part III. Synthesis and Structures of N-Aryloxyacylazoles

Abstract

With the aim of obtaining plant growth regulators, we have synthesized 1-aryloxy-acylbenzimidazoles, 1-aryloxyacylindazoles, 2-aryloxyacyl-4, 5, 6, 7-tetrahydroindazoles and 1-aryloxyacylbenzotriazoles by the acylation of azoles, and I-aryloxyacyl-4, 5, 6, 7-tetrahydro-indazoles by the reaction of aryloxyacylhydrazines with 2-(hydroxymethylene)cyclohexanone. The structures of these compounds are discussed on the basis of nuclear magnetic re-sonance data.
