简易方法制备二甲基二硒

Preparation of Dimethyl Diselenide with Simple Method

二甲基二硒是合成功能含硒有机物的一个重要中间体。该物质合成的传统方法在不同程度上存在原料相对难得,操作较复杂等不足。本文以硒粉、硼氢化钾为主要原料,采用简易的方法合成了二甲基二硒,总收率达81.6%。并通过IR、1HNMR、13CNMR和GC-MS进行了表征。

Dimethyl diselenide was an important intermediate for synthesis of functional organic selenium.The raw material was relatively difficult to obtain and the operation process was relatively complex in the traditional method.In this paper,dimethyl diselenide was synthesized with a simple method using selenium powder and potassium borohydride as the main raw material in a yield of 81.6%,and it was characterized by IR,^1HNMR,^13CNMR and GC-MS.
