Diiron nonacarbonyl in combination with triphenylphosphine has been identified as a low-cost and environmentally benign catalyst system for the allylation of zinc enolates generated in situ from copper-catalyzed asymmetric conjugate addition reactions. The catalyst system provides the allylated product in modest to good yields at room temperature with unprecedented diastereoselectivity in cyclic enone
二铁九碳羰基铁与三苯基膦的组合已被认为是一种低成本且对环境无害的催化剂体系,用于烯丙基化铜催化的不对称共轭加成反应原位生成的烯醇锌的烯丙基化。该催化剂体系在室温下以适中至良好的产率提供烯丙基化产物,并且在环状烯酮体系中具有空前的非对映选择性。尽管三苯膦在所研究的配体中是唯一有效的,但活性催化物质的确切性质仍然未知。
