Chemodivergent cross-couplings are those in which either one of two (or more) potentially reactive functional groups can be made to react based on choice conditions. In particular, this review focuses involving different (pseudo)halides that compete for the role electrophilic coupling partner. The discussion is primarily organized by pairs electrophiles including chloride vs. triflate, bromide ...

Within the last decades the transition metal-catalyzed cross-coupling of non-activated alkyl halides has significantly progressed. Within the context of alkyl-alkyl cross-coupling first row transition metals spanning from iron, over cobalt, nickel, to copper have been successfully applied to catalyze this difficult reaction. The mechanistic understanding of these reactions is still in its infan...

We reported herein the regio- and stereoselective palladium-catalyzed cross-coupling reactions of unsaturated organoselenides with Sonogashira, Suzuki, Negishi and Kumada partners. The reactions were in general carried out with Pd(PPh3)4 (10 mol%), in DMF at 80 °C to afford the cross-coupling products in good yields. This strategy tolerated a wide range of substrates, such as alkynyl, vinyl, ar...

unique status among methods for the construction of carbon– carbon bonds. The well-established Stille–Migita–Kosugi coupling of organostannanes and the Suzuki–Miyaura coupling of organoboron compounds are two reactions that, until recently, have been the “gold-standard” among various palladium-catalyzed coupling reactions. Their wide use and extraordinary synthetic utility have provided the imp...

The cross-coupling reaction between phenylboronic acid and various types of aryl halides (Suzuki reaction) was carried out using a catalytic amount of a new palladium catalyst (1-benzyl-3-(1-benzyl-1-methylpyrrolidin-1-ium-2-yl) pyridin-1-ium palladium chloride [DBNT][PdCl4]) in poly (ethylene glycol) (PEG-200) in the presence of KOH as the base. This new catalyst was synthesized and...

Synchronization of oscillatory EEG signals across different frequency bands is receiving waxing interest in cognitive neuroscience and neurophysiology, and cross-frequency coupling is being increasingly linked to cognitive and perceptual processes. Several methods exist to examine cross-frequency coupling, although each has its limitations, typically by being flexible only over time or over fre...

Several Hiyama cross-coupling reactions of oxasilacycloalkenes and aryl iodides are described that produce trisubstituted Z-styrenes in moderate to excellent yields. Both electron-rich and electron-poor aryl iodides are tolerated in the cross-coupling reaction. The oxasilacycloalkene coupling partners were prepared by ruthenium-catalyzed intramolecular anti-hydrosilylation of alkynols. One of t...
