Acyclic diaminocarbenes are found to be useful ligands for palladium catalyzed Suzuki-Miyaura, Sonogashira and Heck cross-coupling reactions of aryl/alkenyl bromides and chlorides.

A new dimeric orthopalladated complex was synthesized via reaction of 2,3-dimethoxy benzaldehyde oxime with palladium chloride and lithium chloride in methanol as solvent and sodium acetate as base at room temperature. The catalytic activity of this dimeric [Pd{C6H2(-CH=NOH)-(OMe)2-2,3}(µ-Cl)]2 complex as an efficient, air, and moisture tolerant catalyst was investigated in Mizoroki–Heck cross ...

Halogenated quinazolinones and quinazolines are versatile synthetic intermediates for the metal-catalyzed carbon-carbon bond formation reactions such as the Kumada, Stille, Negishi, Sonogashira, Suzuki-Miyaura and Heck cross-coupling reactions or carbon-heteroatom bond formation via the Buchwald-Hartwig cross-coupling to yield novel polysubstituted derivatives. This review presents an overview ...

Considerable efforts have been undertaken by numerous groups in academia and industry over the past decade to expand the repertoire of coupling reagents in palladium(0)-catalyzed cross-coupling reactions. In particular, alkenyl phosphates and tosylates have proven their worth in various cross-coupling reactions, such as the Stille, Suzuki, 3] Negishi, Kumada, Sonogashira, b,e,f,5] Buchwald–Hart...
