Simple and efficient nickel-catalyzed cross-coupling reaction of alkynylalanes with benzylic and aryl bromides.
Highly efficient and simple coupling reactions of benzylic and aryl bromides with aluminium acetylide catalyzed by NiCl(2)(PPh(3))(2) are reported. The coupling reactions proceed at room temperature employing 4 mol% catalyst, affording coupling products in excellent yields of up to 95% in short reaction times. The system worked efficiently with aryl and heterocyclic bromides as well.
متن کاملNickel-catalyzed cross-coupling of aryltrimethylammonium triflates and amines.
Nickel-catalyzed cross-coupling of aryltrimethylammonium triflates and amines was carried out under mild conditions. The reaction has a broad scope of substrates and can be performed by a one-pot procedure from an aryldimethylamine.
متن کاملNickel-Catalyzed Asymmetric Reductive Cross-Coupling To Access 1,1-Diarylalkanes.
An asymmetric Ni-catalyzed reductive cross-coupling of (hetero)aryl iodides and benzylic chlorides has been developed to prepare enantioenriched 1,1-diarylalkanes. As part of these studies, a new chiral bioxazoline ligand, 4-heptyl-BiOX (L1), was developed in order to obtain products in synthetically useful yield and enantioselectivity. The reaction tolerates a variety of heterocyclic coupling ...
متن کاملEnantioselective alkenylation via nickel-catalyzed cross-coupling with organozirconium reagents.
A new family of organometallic compounds, organozirconium reagents, are shown to serve as suitable partners in cross-coupling reactions of (activated) secondary alkyl electrophiles. Thus, the first catalytic method for coupling secondary alpha-bromoketones with alkenylmetal reagents has been developed, specifically, a mild, versatile, and stereoconvergent carbon-carbon bond-forming process that...
متن کاملNickel-catalyzed cross-coupling of diarylamines with haloarenes.
The cross-coupling reaction of diarylamines with aryl bromides/iodides can be effected by the Ni(ii)-(sigma-aryl) complex/PPh(3)/NaH system, and a preliminary investigation was conducted into the mechanism of this reaction.
