Carbon-13 NMR shifts of bridging hydrocarbyls derived from the addition of nucleophiles to complexed organic ligands in DI- and polynuclear complexes
Autor: Arthur J. Carty, Andrew A. Cherkas, Susan M. Breckenridge
Publikováno v: Polyhedron. 11:1075-1084
13 C NMR data for a range of iron group dinuclear hydrocarbyl fragments derived from nucleophilic addition to μ 2 -η 2 -acetylides and other complexed organic ligands are presented. For μ 2 -vinylidenes C α resonances lie in the range 292.2–297
