A methoxy(alkenyl)carbenerhodium complex [RhCp*Cl{[double bond, length as m-dash]C(OMe)CH[double bond, length as m-dash]CPh2}(PMe3)]PF6 (2) has been synthesized and used as the starting material for the study of the effect of the metal center (Rh vs. Ir) in the formation of new rhodacycle complexes. While η3 and η5 indenylrhodium complexes have been achieved by the C-H bond activation of a phenyl ring, insertion of terminal alkynes into the rhodium-carbene bond led to the first example of the synthesis of rhodafuran complexes through rhoda-1,3,5-hexatriene intermediates. This new method represents an efficient process to obtain metallafuran complexes.
甲氧基(烯基)卡宾钌配合物[RhCp*Cl{[双键,长度为破折号]C(OMe)CH[双键,长度为破折号]CPh2}(PMe3)]PF6(2)已被合成,并用作研究金属中心(Rh 与 Ir)在形成新的铑环配合物中的作用的起始物质。虽然通过芳基环的 C-H 键活化已经实现了 η3 和 η5 茚基铑配合物,但末端炔烃插入到铑-卡宾键中导致了通过 rhoda-1,3,5-己三烯中间体合成 rhodafuran 配合物的首例。这种新方法代表了获得金属呋喃配合物的有效过程。
