Abstract:

¹³C NMR spectra of 6 new kinds of N-(2-phenyl-1,2,3-triazole-4-actyl)- N′-Arylt hioureas are reported in this paper. These compounds will have potential applica tion value for the use  as plant growth regulators，antitumor medicine or ch emical picki ng agent for fruits. By testing the ¹³C NMR spectra, the structures have been d etermined and all ¹³C NMR peaks have been assigned. The effects of str ucture on  the chemical shifts are discussed. At the same time, the subtituent parameters o f the two new substituent (R₁ and R₂) are given.

Key words: N-(2-phenyl-1,2,3-triazole-4-actyl)-N′-Arylthioureas,  ¹³C NMR, Chemical shift, Molecular structure
