Access to Macrocycles with an endo Aryl Ether and an endo Aryl-Aryl Bond, Development and Application

open access: yesCHIMIA, 2011
Macrocyclization methodologies allowing access to macrocycles having an endo aryl ether and an endo aryl–aryl bond, especially those based on an intramolecular SNAr reaction and the Suzuki-Miyaura reaction, are summarized.

Palladium-Catalyzed Esterification of Aryl Fluorosulfates with Aryl Formates

open access: yesMolecules
An efficient palladium-catalyzed carbonylation of aryl fluorosulfates with aryl formates for the facile synthesis of esters was developed. The cross-coupling reactions proceeded effectively in the presence of a palladium catalyst, phosphine ligand, and ...

Reversible Dehalogenation in On‐Surface Aryl–Aryl Coupling [PDF]

open access: yesAngewandte Chemie International Edition, 2020
AbstractIn the emerging field of on‐surface synthesis, dehalogenative aryl–aryl coupling is unarguably the most prominent tool for the fabrication of covalently bonded carbon‐based nanomaterials. Despite its importance, the reaction kinetics are still poorly understood.

Aryl–Aryl Interactions in (Aryl‐Perhalogenated) 1,2‐Diaryldisilanes

open access: yesChemistry – A European Journal, 2020
AbstractThree 1,2‐diaryltetramethyldisilanes X5C6‐(SiMe2)2‐C6X5 with two C6H5, C6F5, or C6Cl5 groups were studied concerning the importance of London dispersion driven interactions between their aryl groups. They were prepared from 1,2‐dichlorotetramethyldisilane by salt elimination.

Efficient Copper-Catalyzed N-Arylation of Sulfoximines with Aryl Iodides and Aryl Bromides [PDF]

open access: yesThe Journal of Organic Chemistry, 2005
Two simple and inexpensive systems for copper-catalyzed N-arylations of sulfoximines with aryl bromides and aryl iodides have been developed. Using 10 mol % of a copper(I) salt in combination with 20 mol % of a 1,2-diamine and Cs2CO3 provides N-arylated sulfoximines in high yields. Various functional groups and heteroatoms are tolerated.

Direct Introduction of a Dimesitylboryl Group Using Base-Mediated Substitution of Aryl Halides with Silyldimesitylborane [PDF]

open access: yes, 2016
The first dimesitylboryl substitution of aryl halides with a silylborane bearing a dimesitylboryl group in the presence of alkali-metal alkoxides is described.

High throughput synthesis of 2,5-substituted indoles using a titanium carbenoid bearing boronate functionality [PDF]

open access: yes, 2008
A titanium benzylidene complex bearing a boronate group converted resin-bound esters into enol ethers. Suzuki cross-coupling with aryl iodides followed by cleavage with acid completed the solid-phase synthesis of 2,5-disubstituted N-Boc-indoles.
