Nickel (II) Catalyzed Cross-Coupling with Grignard Reagents (Kumada Reaction) Pure AppJ. Chem. 1980, 52, 669 Bull Chern. Soc.Jpn. 1976, 49, 1958... [Pg.113]

CROSS-COUPLING OF ARYLCHLORIDES WITH ARYL GRIGNARD REAGENTS (KUMADA REACTION)... [Pg.211]

The Kumada cross-coupling reaction (also occasionally known as the Kharasch cross-coupling reaction) is a nickel- or palladium-catalyzed cross-coupling reaction of a Grignard reagent with an organic halide, triflate, etc. [Pg.345]

A few palladium-catalyzed Kumada cross-couplings of heteroaryl chlorides have been reported [101]. Knochel has recently determined that certain 2-chloropyridine derivatives react with functionalized aryl Grignard reagents under mild conditions (Equation 2.61) [102]. [Pg.52]

Cross-couplings between organotin (Stille type), Grignard reagent (Kumada type), and aryl halide have been carried out using palladium over silica support. ... [Pg.1347]

The synthesis of a 3-alkylthiophene mcMiomer can be achieved in several different ways. One rather simple way involves Kumada cross-coupling of 3-bromothiophene (9) with an alkyl Grignard reagent, as seen in Scheme 4 [52]. [Pg.210]

Nickel bisphosphine complexes are used as catalysts in cross-coupfing of aromatic and olefinic halides with Grignard reagents. Kumada and co-workers [69] reported a cross-coupling reaction... [Pg.567]
