Journal ArticleDOI
Organopalladium(IV) chemistry
TL;DR: The stoichiometric reactions of Pd(IV) complexes are described and their potential mechanism in catalytic reactions is discussed, leading to the design and development of novel reactions that could not be accessed by traditional Pd (0)/Pd(II) chemistry.
Journal ArticleDOI
Transient Directing Groups for Transformative C–H Activation by Synergistic Metal Catalysis
TL;DR: The emergence of transient directing group approaches through the in situ installation and deconstruction of a Lewis-basic entity with the aid of co-catalytic additives for selective C–H functionalizations is discussed.
Journal ArticleDOI
Metal-catalyzed direct alkylations of (hetero)arenes via C–H bond cleavages with unactivated alkyl halides
TL;DR: C-H bond functionalizations were accomplished with beta-hydrogen-containing alkyl halides in the presence of palladium, nickel or ruthenium catalysts under basic reaction conditions, rendering this approach an attractive alternative to traditional alkylation strategies.

1,4-migration of rhodium and palladium in catalytic organometallic reactions.
Shengming Ma,Zhenhua Gu +1 more
TL;DR: This minireview summarizes the results in this area of the 1,4-metal migration reaction, which is proposed to proceed by the reductive elimination of trivalent intermediates for the Rh-involved reactions and of tetravalents for the Pd-catalyzed processes.
Journal ArticleDOI
Ortho C ? H Acylation of Aryl Iodides by Palladium/Norbornene Catalysis
TL;DR: A palladium/norbornene-catalyzed ortho-arene acylation of aryl iodides by a Catellani-type C-H functionalization is reported, enabled by isopropyl carbonate anhydrides, which serve as both an acyl cation equivalent and a hydride source.

On the efficiency of tetraalkylammonium salts in heck type reactions
TL;DR: Under appropriate conditions, tetraalkylammonium hydrogensulfate can be just as efficient as bromide for facilitating Heck-type reactions as discussed by the authors, and an appropriate selection of the [Pd / Base / QX] catalyst system can allow this type of reactions to be efficiently realised at will, in a strictly anhydrous medium, in water-orgamic solvent mixture or in water alone.

Palladium in action: domino coupling and allylic substitution reactions for the efficient construction of complex organic molecules
Armin de Meijere,Stefan Bräse +1 more
TL;DR: The Heck reaction has been applied to a number of new concepts starting from simple, oligohalogenated alkenes and arenes, and the synthesis of a variety of highly functionalized carbon skeletons has been established.
