摘要

Abstract Intramolecular carbenoid C [BOND] H insertion of five α-diazoacetamides [N 2 CH [BOND] CONR 2, NR 2= NEt 2 (3a), NBu 2 (3b), N (i-Pr) 2 (3c), N (CH 2 Ph) 2 (3d), N (i- Pr)(CH 2 Ph)(3e)], was investigated using as catalysts dinuclear Ru (I, I) complexes of the type [Ru 2 (μ-L 1) 2 (CO) 4 L 2 2], where L 1 is a bidentate bridging acetate, calix [4] arenedicarboxylate, saccharinate, pyridin-2-olate, or triazenide ligand, as well as [RuCl 2 ( ...
