tetracarbonyl phosphine and tertiary amine complexes [M(CO)4 L2, M = Cr, Mo, W, L2 = 2PPh3, dppm, dppe, dppp, dppb, bpy, phen, dppf] were synthesized in minutes in the microwave at moderate temperature, atmospheric pressure, and utilizing NaBH4 as a catalyst. The reactions were optimized by careful solvent selection. The octahedral complexes were isolated in percent yields ranging from 17 to 95. The
摘要 在几分钟内合成了几种 VI 族四羰基膦和叔胺配合物 [M(CO)4 L2, M = Cr, Mo, W, L2 = 2PPh3, dppm, dppe, dppp, dppb, bpy, phen, dppf]在中等温度、大气压下进行微波,并利用 NaBH4 作为催化剂。通过仔细选择溶剂来优化反应。八面体配合物以 17 到 95% 的产率被分离出来。与传统的热合成相比,更低的温度、更短的反应时间、温和的溶剂和更低的压力为这些常见的 VI 族配合物提供了一种快速、环保的合成途径.
