Structural Characterization of Heterodimetallic Zr/Pd and Zr/Rh Catalyst Precursors Containing the C5H4PPh2 Ligand
(Cp-PPh2)2ZrCl2 (5) reacts with (PhCN)2PdCl2 to yield the early-late heterodimetallic complex [(Cp-PPh2)2ZrCl2/PdCl2], 7, which was characterized by an X-ray crystal structure analysis. The phosphine-substituted bent metallocene moiety in 7 serves as a conformationally flexible chelate phosphine ligand (angle P-Pd-P: 96.46(3)). Complex 7 is an active catalyst for the cross-coupling of sec-butylmagnesium bromide with bromobenzene, leading to excellent regioselectivity and moderate reactivity. Complex 5 reacts with dicarbonylrhodium chloride dimer (0.5 equiv) to yield the triply bridged complex 12, [ClZr(mu-Cp-PPh2)2-(mu-Cl)Rh(CO)Cl], which was also characterized by X-ray diffraction (the angle P-Rh-P is 158 at the distorted square-pyramidal pentacoordinated rhodium center). (Cp-PPh2)2Zr-(CH3)2 (13) reacts with [H(CO)Rh(PPh3)3] (14) with loss of two PPh3 ligands and instantaneous liberation of methane to form complex 15, [CH3Zr(mu-Cp-PPh2)2Rh(CO)PPh 3](Zr-Rh), which probably contains a metal-metal bond between the early and late transition metal. Complex 15 is a very active 1-hexene hydroformylation catalyst (TOF > 600, n/iso ? 3 at 80C).
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 72287-26-4
