A General, Efficient, and Functional-Group-Tolerant Catalyst System for the Palladium-Catalyzed Thioetherification of Aryl Bromides and Iodides

On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially wit...

Cross-Coupling of Mesylated Phenol Derivatives with Potassium Cyclopropyltrifluoroborate

A robust and efficient protocol for the introduction of the dioxolanylethyl moiety onto various aryl and heteroaryl halides has been developed, providing cross-coupling yields up to 93%. Copper-catal...

Determination of Water Content in n-Hexane Using Karl Fischer Titration

Water determination in hydrocarbons is relatively straightforward. Lower hydrocarbons dissolve in methanol, however, even if the dissolution is incomplete, the water is rapidly extracted and complete...

Highly Reactive, General and Long-Lived Catalysts for Palladium-Catalyzed Amination of Heteroaryl and Aryl Chlorides, Bromides, and Iodides: Scope and Structure-Activity Relationships

Boronic acids which quickly deboronate under basic conditions, such as polyfluorophenylboronic acid and five- membered 2-heteroaromatic boronic acids, are especially chal- lenging coupling partners f...

Palladium-catalyzed coupling of functionalized primary and secondary amines with aryl and heteroaryl halides: two ligands suffice in most cases

We report our studies on the use of two catalyst systems, based on the ligands BrettPhos and RuPhos, which provide the widest scope for Pd-catalyzed C-N cross-coupling reactions to date. Often low ca...

Palladium-catalyzed inter- and intramolecular cross-coupling reactions of B-alkyl-9-borabicyclo[3.3.1]nonane derivatives with 1-halo-1-alkenes or haloarenes. Syntheses of functionalized alkenes, arenes, and cycloalkenes via a hydroboration-coupling sequence

The cross-coupling reaction of B-alkyl-9-borabicyclo[3.3.l]nonanes (B-R-9 BBN), readily obtainable from alkenes by hydroboration, with 1-halo-1-alkenes or haloarenes in the presence of a catalytic am...
