The coupling of aryl or vinyl halides with terminal acetylenes catalysed by palladium and
other transition metals, commonly termed as Sonogashira cross-coupling reaction, is one of …

1. INTRODUCTION Bulk gold, being the most stable among all metals, was for many years
considered as an inert catalyst. However, gold particles with size on the scale of nanometers …

Gold has been used for coinage, jewelry, and other arts for thousands of years due to its
stability in air. Catalytic researchers were long misled by this common sense until the …

Although already established as distinct areas of practice by chemists by the late 19th
century, a formal distinction between homogeneous and other types of catalysis was only …

A key challenge in the field of nanotechnology, in particular in the design of molecular
machines, novel materials or molecular electronics, is the bottom-up construction of …

On-surface synthesis is the bottom-up construction of covalent bonds between molecular
building blocks, which has been greatly developed during the past decade. Dozens of …

The covalent linking of acetylenes presents an important route for the fabrication of novel
carbon-based scaffolds and two-dimensional materials distinct from graphene. To date few …

We report on a stepwise on-surface polymerization reaction leading to oriented graphene
nanoribbons on Au (111) as the final product. Starting from the precursor 4, 4 ″-dibromo-p …

Conspectus The covalent linking of acetylene compounds is an important synthetic tool to
control carbon–carbon bond formation and has been extensively studied for more than a …

We report on a combined scanning tunneling microscopy (STM), X-ray photoelectron
spectroscopy (XPS), and density functional theory (DFT) study on the surface-assisted …
