本文报道了5，10，15，20-四均三甲苯基卟啉的阴离子RuII（TMP）在苯或甲苯溶液中与乙炔和烯烃的反应。乙炔产生可分离的[Ru（TMP）]2（μ-C2 H2）物种;而与苯乙炔或二苯基乙炔形成1：1 π-络合物。从与乙烯的反应中分离出了Ru（TMP）（C2 H4）和Ru（TMP）-（C2 H4）（iPrOH）·iPrOH的π-配合物，并原位表征了类似的环己烯物种。研究结果与反式Ru（TMP）（O）2配合物催化烯烃的O2-环氧化反应有关。关键词：钌、卟啉、烯配合物、炔配合物。
The reactions of benzene or toluene solutions of RuII(TMP), where TMP is the dianion of 5,10,15,20–tetramesitylporphyrin, with some acetylenes and alkenes are reported. Acetylene yields the isolable [Ru(TMP)]2(μ-C2H2) species; while with phenylacetylene or diphenylacetylene, 1:1 π-complexes are formed. The π-complexes Ru(TMP)(C2H4) and Ru(TMP)-(C2H4)(iPrOH)•iPrOH are isolated from reactions with ethylene, and a similar cyclohexene species is characterized insitu. The findings are relevant to O2-epoxidation of alkenes catalyzed by the trans-Ru(TMP)(O)2 complex. Keywords: ruthenium, porphyrin (tetramesityl), alkene complexes, alkyne complexes.
