    PHOSPHINE-UREA LIGANDS FOR TRANSITION METAL CATALYZED CROSS-COUPLING REACTIONS
    摘要:
    Carbon-carbon bond forming reactions are the cornerstone of organic chemistry. A new class of ligands was developed for transition metal catalyzed cross-coupling reactions. These phosphine-urea ligands incorporate a urea subunit into the backbone of the ligand, which is designed to bind to the organometallic coupling partner and simultaneously facilitate and direct transmetalation of the nucleophile. Synthetic routes were designed and executed to synthesize phosphine-urea ligands. These ligands catalyze a wide variety of cross-coupling reactions including Suzuki, Negishi, and Buchwald-Hartwig cross-couplings. Aryl-aryl, alkyl-aryl, and alkyl-alkyl C—C cross-couplings are performed successfully with these ligands. In addition, specific chiral phosphine-urea ligands catalyze Negishi cross-couplings enantioselectively from a racemic alkylzinc nucleophile.

    We describe the unprecedented formation of allenes by Ni‐catalyzed cross‐coupling of propargyl bromides with alkylzinc halides. The reaction regioselectivity is complementary to the previously reported formation of propargyl‐coupled compounds. Experiments support the formation of NiI complexes as the active species and the participation of radical intermediates. Kinetic studies showed that the reaction

    general procedure for the nucleophilic addition of organozinc halides with nitrones in the presence of trimethylsilyl chloride has been developed. Trimethylsilyl chloride was found to be both an indispensable reaction promoter and a ready hydroxylamine protective agent in these reactions. The produced O-(trimethylsilyl)hydroxylamines can be easily reduced into corresponding amines just by a zinc–copper

    organometallic reagents represents a convergent route toward complex and versatile ketone products. Despite the mild conditions and high functional group tolerance, the cross-coupling of carboxylic acid derivatives, such as thioesters, and secondary organometallic reagents is an underdeveloped transformation. Herein, we disclose a convenient and efficient protocol for the Pd-catalyzed Fukuyama cross-coupling
