molecular wires, alkyne metathesis was investigated as an alternative to palladium-catalyzed coupling reactions for the synthesis of alkynyl ferrocenes. With a Mortreux catalyst system [Mo(CO)6, 4-chloro- or 2-fluorophenol], (1-propynyl)ferrocenes gave the expected homo metathesis products in moderate yields. Because the Mortreux catalyst system is not compatible with 1,1′-dialkynylferrocenes, a nitridomolybdenum
在基于二茂铁的分子线的构建中,研究了炔复分解作为钯催化偶联反应的替代方法,用于合成炔基二茂铁。使用 Mortreux 催化剂系统 [Mo(CO)6, 4-氯-或 2-氟苯酚],(1-丙炔基)二茂铁以中等产率得到预期的均位复分解产物。由于 Mortreux 催化剂体系与 1,1'-二炔基二茂铁不相容,Furstner 引入的氮钼催化剂在双向均和交叉炔复分解反应中进行了测试。尽管以低产率获得均炔复分解产物,但交叉炔复分解反应以良好的总产率提供了预期的产物。
