While remote functionalization via chain walking has the potential to enable access to molecules via novel disconnections, such processes require relatively long reaction times and can be in need of elevated temperatures. This work features a remote arylation in less than 10 min reaction time at room temperature over a distance of up to 11 carbons. The unprecedented speed is enabled by the air-stable PdI dimer [Pd(μ-I)(PCy2tBu)]2, which in contrast to its PtBu3 counterpart does not trigger direct coupling at the initiation site, but regioconvergent and chemoselective remote functionalization to yield valuable fluorinated 1,1-diaryl alkanes. Our combined experimental and computational studies rationalize the origins of switchability, which are primarily due to differences in dispersion interactions.
Effect of composition on the catalytic properties of mixed-ligand-coated gold nanoparticles

Striped catalysts: The effect of composition and structure on the catalytic efficiency of gold nanoparticles protected by a monolayer composed of two types of ligands differing in length (see picture) is reported. By diluting catalytically active ligand molecules with simple catalytically inactive molecules the catalytic efficiency of the particles is enhanced.
Dangling arms: A tetrahedral supramolecular host with partially encapsulated guests

, p. 83 - 86 (2007/10/03)
A protruding tail: A guest composed of a cationic sandwich complex, an alkyl chain, and a sulfonate anionic group is partially incorporated within a host [Ga4L6]12- cluster (see scheme). The cationic head group is quickly incorporated into the cavity of the host, while the sulfonate unit at the other end of the chain is not, as the alkyl sulfonate tail protrudes through an opening in a triangular face of the tetrahedral cluster. (Figure Presented).
