摘要:

在微波甲醇溶剂热中,正丁基三氯化锡(n-BuSnCl3)与双[4-二乙氨基或(3,5-二叔丁基)取代水杨醛]缩卡巴肼和缩硫代卡巴肼配体反应,合成双(取代水杨醛)缩卡巴肼和缩硫代卡巴肼丁基锡配合物,( n-BuSn) 2CI3(OH2)[(2-OH,R)PhCH=NNH]2CX[R:4-NEt2(4-二乙氨基),X:O(A1);R:4-NEt2,X:S(A2);R:3,5-(t-Bu)2,X:O(A3);R:3,5-(t-Bu)2,X:S(A4)],经元素分析、IR、1H 和 13C NMR表征,X射线衍射获得的配合物A2的晶体结构表明,化合物A2是具有六配位畸形八面体构型的双锡核配合物。 配体及其丁基锡配合物均对马齿苋、刺苋、四九菜心、苋菜和决明子靶标植物具有生长抑制作用,且配合物A1和A2具有较广谱、配合物A3和A4具有选择性生长抑制作用,可作为杂草生长抑制候选物研究。

Abstract:

Four n-butyltin complexes, ( n-BuSn) 2CI3(OH2)[(2-OH,R)PhCH=NNH]2CX [R:4-NEt2, X:O(A1); R:4-NEt2, X:S(A2); R:3,5-(t-Bu)2, X:O(A3); R:3,5-(t-Bu)2, X:S(A4)], were obtained by microwave-assisted solvothermal reaction of n-butyltintrichloride(n-BuSnCl3) with bis(4-diethylamino or 3,5-di-t-butyl salicylaldehyde)carbohydrazide and thiocarbohydrazide in methanol environments, which were characterized by elemental analysis, IR, 1H NMR, and 13C NMR spectra. The crystal structure of complex A2 shows a binuclear hexacoordinated distorted octahedral configuration. The ligands and their butyltin complexes inhibit the growth of plants, such as Portulaca oleracea, Amaranthus spinosus, Brassica campestris ssp. chinensis var. Utilis, Amaranthus tricolor and Cassia tora. Complexes A1, A2 have a broad range of growth inhibition activity, while complexes A3 and A4 have selective inhibitory activity. They can be used as candidate herbicides for weed growth inhibition.

Key words: bis(substituted salicylaldehyde) carbohydrazide butyltin complex, crystal struture, herbicidal activity
