Through-conjugation of two phosphaalkyne moieties within an isolable molecule is demonstrated for the first time with the synthesis of [{Ru(dppe)2}2{μ-(C[triple bond, length as m-dash]C)2C6H4-p}(C[triple bond, length as m-dash]P)2], via base-induced desilylation of [{Ru(dppe)2}2{μ-(C[triple bond, length as m-dash]C)2C6H4-p}(η1-P[triple bond, length as m-dash]CSiMe3)2]2+. The nature of the cyaphide ligands and their influence upon the bimetallic core are studied electrochemically.
通过[{Ru(dppe)₂}₂{μ-(C≡C)₂C₆H₄-p}(η¹-P≡CSiMe₃)₂]²⁺的碱诱导去硅基化反应,首次合成了[{Ru(dppe)₂}₂{μ-(C≡C)₂C₆H₄-p}(C≡P)₂],从而在一个可分离的分子中实现了两个磷炔部分的直接共轭。通过电化学方法研究了氰基配体的性质及其对双金属核的影响。
