Mechanistic Investigations of Nickamine-catalyzed Hydrosilylation of Alkenes: Nickel Nanoparticles Are the Active Species

Xile Hu, Marten Leendert Ploeger

Hydrosilylation is an important chemical process for the synthesis of organosilanes and for the production of silicone polymers. The wide variety of catalysts developed for this reaction generally follow a Chalk-Harrod, or a sigma-bond metathesis mechanism ...

Are pi-pi Interactions in Ionic Liquids Related to Conductivities?

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Farzaneh Fadaei Tirani, Zhangjun Huang

A series of functionalised imidazolium halide salts with substituents able to form pi-bonds have been prepared and characterised. Subsequent reaction of these imidazolium halides with Ag[C(CN)(3)] affords imidazolium-based ionic liquids (ILs), some of whic ...

An Easily Accessed Nickel Nanoparticle Catalyst for Alkene Hydrosilylation with Tertiary Silanes

Xile Hu, Ivan Buslov, Fang Song

The first efficient and non-precious nanoparticle catalyst for alkene hydrosilylation with commercially relevant tertiary silanes has been developed. The nickel nanoparticle catalyst was prepared in situ from a simple nickel alkoxide precatalyst Ni((OBu)-B ...

Nickel-catalyzed Hydrosilylation of Alkenes and Transition-Metal-Free Intermolecular α-C-H Amination of Ethers

Ivan Buslov

Transition-metal-catalyzed hydrosilylation of olefins is one of the most important methods for the preparation of organosilicon compounds, which have broad applications in both synthetic and material chemistry. For decades, precious metals, principally pla ...

Band offsets at Ge/GeO2 interfaces: Effect of different interfacial bonding patterns

Alfredo Pasquarello, Peter Broqvist, Jan Felix Binder

Using hybrid density functional calculations, we investigate possible origins for the large variation of band offsets measured at Ge/GeO2 interfaces. We consider atomistic model interfaces with both amorphous and crystalline oxides, in which the bond densi ...

Cycloadditions to control bond breaking in naphthalenes, fullerenes, and carbon nanotubes: A first-principles study

Nicola Marzari

Covalent functionalizations represent a very promising avenue to engineer or manipulate carbon nanotubes. However, in metallic tubes the electrical conductance can drop by several orders of magnitude following functionalization, due to sp(3) rehybridizatio ...

Base-promoted elimination of hydrogen fluoride from alkyl fluorides: reactivity and stereochemistry

The alcoholate-promoted dehydrohalogenation of 5-nonyl fluoride and cyclododecyl fluoride, typical straight-chain and, resp., medium-size cyclic substrates, leads to cis- and trans-alkenes in an approx. ratio of 1:3. With bulky bases such as lithium diisop ...
