Reaction of 1,2-bis(diphenylphosphino)benzene (dppbz) with [{Ru(CO)₂Cl₂}_n] affords [Ru(dppbz)(CO)₂Cl₂], where the two carbonyls are mutually cis and the two chlorides are trans. The molecular structure of [Ru(dppbz)(CO)₂Cl₂], has been determined by X-ray crystallography, and the stability of the different available stereoisomers has been computationally evaluated. [Ru(dppbz)(CO)₂Cl₂] has been found to serve as an excellent pre-catalyst for catalytic Suzuki-type C–C coupling and Buchwald-type C–N coupling reactions.

一种新的钌二膦-羰基配合物：CC和C-N键偶联催化的有效前体†

1,2-双（二苯基膦基）苯（dppbz）与[{Ru（CO）₂ Cl ₂ } _n ]反应，得到[Ru（dppbz）（CO）₂ Cl ₂ ]，其中两个羰基相互为顺式，而两个羰基为顺式。两个氯化物是反式的。[Ru（dppbz）（CO）₂ Cl ₂ ]的分子结构已通过X射线晶体学测定，并且已通过计算评估了各种可用的立体异构体的稳定性。[Ru（dppbz）（CO）₂ Cl ₂ ]被发现是催化Suzuki型C–C偶联和Buchwald型C–N偶联反应的出色预催化剂。
