摘要

用取代的4-氧代铬-3-羧基1与2-甲基苯并噻唑(2a)或2-甲基苯并恶唑(2b)和苯并溴化苄进行一锅缩合反应，简便地合成了新型2-(4-氧代铬-3-基)苯并噻唑溴4和苯并恶唑溴5。研究了苯并噻唑溴铵对黄瓜生长的促进作用和对玉米幼苗的阻燃作用。它们在10 - 100 ppm的浓度范围内抑制黄瓜(根和下胚轴)和玉米芽的生长，在0.1 - 1 ppm的浓度范围内刺激。

Synthesis and plant growth activity of 2-(4-oxochromen-3-yl)benzothiazolium and -benzoxazolium bromides

A facile synthesis of novel 2-(4-oxochromen-3-yl) benzothiazolium bromides 4 and benzoxazolium bromide 5 using the one-pot condensation of substituted 4-oxochromene-3-carboxaldehydes 1 with 2-methylbenzothiazole (2a) or 2-methylbenzoxazole (2b) and benzyl bromide is described. The effects of benzothiazolium bromides 4 on the growth stimulation of the cucumber and retardant activity on corn seedlings were investigated. They inhibited growth of cucumber (root and hypocotyl) and shoots of corn at the range of 10 – 100 ppm and stimulated at 0.1 – 1 ppm concentrations.
