Abstract
Abstract Trifluoromethyl isocyanide adds to the metal—metal triple bond of bis[dicarbonyl(η-pentamethylcyclopentadienyl)molybdenum] forming Mo 2 Cp 2 ★ (CO) 4 (η 2 -μ-CNCF 3 ) as the first isolated product. Further addition of trifluoromethyl isocyanide at 0°C leads to the formation of [Mo(CO) 2 (μ-CNCF 3 )(η-Cp ★ )] 2 , which according to crystal structure analysis contains two bridging CF 3 NC ligands. During the isomerization of this compound in dichloromethane solution at room temperature or in the solid state above 110°C molybdenum—molybdenum bond cleavage and carbon—carbon bond formation occurs, leading to Cp ★ (CO) 2 Mo(μ-F 3 CNCCNCF 3 )Mo(CO) 2 Cp ★ , which contains 1,1,1,6,6,6-hexafluoro-2,5-diaza-2,3,4-hexatriene as bridging ligand.
