Vinyl homologation via methyl migration to µ-vinyl at a diruthenium centre

Additions and intramolecular migrations of nucleophiles in cationic diruthenium μ-allenyl complexes

“…The reaction which leads to 4c is accompanied by fragmentation, since small amounts (12%) of the known monomer [Ru(Cp)(CO) 2 (Br)] [29] were isolated upon chromatography.…”

C–H and P–C(Ph) activation competitive processes caused by interaction with the solvate [cis-Pt(C6F5)2(thf)2]

“…Complex 4 exhibits the three expected vinylic resonances (d H : 6.50, "dt", H a ; 5.11, dd, H b ; 4.49, dd, H b ) in the low field region, which have been assigned according to the data found in the literature for related vinyl bridging complexes, with the H a proton appearing at higher frequencies than the protons in b positions. 29,76- 79 Suitable crystals for X-ray crystallographic studies were obtained for complexes 4 and 5 (Fig. 3, Table 1).…”

Construction of Two-Faced (Hetero)hydrocarbyl Diiron Complexes Mediated by the Interplay of Ligands

“…Dimetallic complexes featuring two adjacent metal centers constitute unique systems in coordination chemistry, in that such a dimetallic core is the simplest framework which benefits from cooperative effects, enabling peculiar reactivity patterns (especially on bridging ligands) otherwise not viable on monometallic complexes. − Thus, dimetallic complexes have been widely investigated as convenient models to clarify and develop chemical transformations mediated by more complex structures wherein the metal–metal synergy plays a key role, such as natural enzymes and metal surfaces. , In this setting, the interest in the reactivity of hydrocarbyl ligands, bridging coordinated in dinuclear metal complexes, ranges from the elucidation of the mechanisms of carbon–carbon bond formation processes (e.g., the Fischer–Tropsch synthesis), − the metal-mediated synthesis of organic compounds, , new organometallic motifs not accessible from conventional procedures, − and the formation of complexes with functionalized ligands supplying useful properties for applications in catalysis, electronics, and medicinal chemistry. − The huge and urgent demand for the development of sustainable synthetic methodologies renders diiron complexes an ideal choice to explore novel organometallic reaction pathways based on the abundance and environmental benignity of iron. ,− …”
