超声波辐射条件下锡（II）催化合成二吲哚基甲烷的方法研究

摘要

An efficient synthesis of bis(indolyl)methanes catalyzed by SnCl2 was developed with good yields.The new method in the presence of ultrasonic irradiation is successful with stoichiometric catalyst, short reaction time and very easily isolation procedure.These prepared products have a wide absorption at the region of 400 -600 nm when excited by ultraviolet of about 370 nm.Their emission peaks are about 440 nm, indicating that these BIMs emit purple light.%研究了一种由 SnCl2催化合成二吲哚基甲烷的高效方法。引用超声波辐射作为反应条件，在反应体系中加入当量的催化剂能够在短时间内合成出二吲哚基甲烷且分离方法简单易行。合成出的系列二吲哚基甲烷具有一定的光学性质，即在400～600 nm 波长范围内范围内具有光吸收作用，且在受波长为370 nm 光的激发下，会发出波长约为440 nm 的紫光。
