Unusual Bond Activations
The unusual reactivity of hafnocene complexes in comparison to their titanium and zirconium analogues was dramatically demonstrated in the recent functionalization of coordinated N2 and the coupling of CO2 and N2 to a substituted hydrazine product. The differences in their structure and bonding were also noticed; for example, the s and p ratio of the diene bonding in (s-cis-h-diene) metallocene...
متن کاملMultiple aromatic C-H bond activations by a dirhenium carbonyl complex.
Multiple aromatic CH activations by a dirhenium complex have provided meta-related dimetallated arene rings in the complexes Re2(CO)8(μ-H)(μ-η2-1,2-μ-η2-3,4-C14H8)Re2(CO)8(μ-H), 3 and Re2(CO)8(μ-H)(μ-η1-1,μ-η1-3-C6H4)Re2(CO)8(μ-H), 4. Both products were characterized structurally by single crystal X-ray diffraction and DFT molecular orbital analyses.
متن کاملEfficient Tracking of Behavior in Complex Hybrid Systems via Hybrid Bond Graphs
For many real-world systems, which exhibit complex, nonlinear, and hybrid behavior, it is important to accurately track and monitor the state and health of these systems. The continuous state estimation problem has been well studied, and a number of extensions of the Kalman filter to nonlinear systems have been proposed. Hybrid state estimation poses an additional challenge, because the model m...
متن کاملActivation of a CH bond in polypyridine systems by acetyl hypofluorite made from F2.
Activation of the relatively inactive polypyridine backbone with strong electrophilic fluorine, originating from acetyl hypofluorite (AcOF) enables attack of the acetoxy moiety at the α position to the heteroatom. Derivatives of bipyridine, phenanthroline and terpyridine systems have been acetoxylated or oxygenated within a few minutes usually in very good yields.
متن کاملFormation of a C-C double bond from two aliphatic carbons. Multiple C-H activations in an iridium pincer complex.
The search for novel, atom-economic methods for the formation of C-C bonds is of crucial importance in synthetic chemistry. Especially attractive are reactions where C-C bonds are formed through C-H activation, but the coupling of unactivated, alkane-type Csp3 -H bonds remains an unsolved challenge. Here, we report iridium-mediated intramolecular coupling reactions involving up to four unactiva...
