chelating alkoxy ligand. Dinitrogen complexes were identified as intermediates in all reactions. At elevated temperature, the carbene complex (p-cymene)Ru(μ-Cl)3RuCl(C2H4)(IMes) is able to catalyze the oxidation of alcohols with N2O.
双核Ru(II)络合物(arene)Ru(μ-Cl)3 RuCl(C 2 H 4)(PCy 3)(亚芳基=对苯甲基或1,3,5-C 6 H 3 i Pr 3)反应在温和条件下用N 2 O生成OPCy 3和三核配合物(芳烃)Ru(μ-Cl)3 Ru(μ-Cl)3 Ru(芳烃)。另一方面,N-杂环卡宾络合物(p- Cymene)Ru(μ-Cl)3 RuCl(C 2 H 4)(IMes)(IMes = 1,3-dimesitylimidazol-2-ylidene)与N反应2个O给出具有螯合烷氧基配体的混合价Ru(II)/ Ru(III)配合物。二氮配合物被确定为所有反应的中间体。在高温下,卡宾络合物(对-cymene)Ru(μ-Cl)3 RuCl(C 2 H 4)(IMes)能够催化醇被N 2 O氧化。
