Cobalt-catalyzed Kumada coupling and the development of a CC ligand and metalation to cobalt
… was developed and optimized for catalytic Kumada coupling of aryl Grignard reagents to sterically encumbered alkyl halides. The substrate scope demonstrates excellent yields for primary alkyl chlorides and bromides, including good performance using neopentyl chloride and neophyl chloride. …

Fused Arene-Based Molecular Systems as Additives for Organic Photovoltaics
… and Grignard metathesis followed by Kumada coupling. The molecular structure of each was confirmed by 1H-NMR and IR analysis respectively. The photophysical properties of the products were also evaluated in solution. The potential applicability of these two novel systems for OPVs will …

C2- and C3-Symmetric Meta-substituted Thienyl Benzenes: A Comparative Synthetic and Structural Study
Suzuki, Stille and Kumada coupling approaches to the syntheses of various C1- and C3- symmetric thienylbenzene compounds (A and B, respectively) are systematically compared. Novel routes are reported for the syntheses of C3-symmetric compounds using Kumada (n = 0) and Stille (n = 1) coupling …

Fused-Molecular Systems for Organic Light Emitting Diodes
… synthesized by Grignard metathesis followed by Kumada coupling reaction. Structural characterizations were performed using 1H, 13C NMR and FTIR analysis. Photophysical properties of these systems were studied in chloroform (CHCl3) solution using UV-visible and Fluorescence spectroscopies. The …

Synthesis of Conjugated Polymers
… The polymerization was realized by Ni-catalyzed Kumada coupling with a chain-growth mechanism. Schlenk equilibrium played a key role in the generation of the monomer for the polymerization. PHOT was fully characterized by various techniques. However, only p-channel activity was observed in …

The asymmetric synthesis of enol phosphates and their application in total synthesis
… an enantioenriched enol phosphate followed by a Kumada cross coupling reaction.The novel Kumada coupling reaction was initially developed for the synthesis of (+)-Sporochnol. With the success encountered in such methodology we further developed the reaction, which, ultimately allowed the cross …
