Mixed organozinc reagent

Aryl-aryl coupling by reaction of halides with organozinc reagents is a useful and mild route for the formation of some mixed biaryls. Such a process has been used in the reaction of pyridylzinc reagents with various iodoaromatic compounds giving good yields of coupled products (equation 65)484 87. [Pg.730]

Mixed bis-sulfonatnide ligands of the type 46 were also prepared and shown to be highly effective for the addition of organozinc reagents to ketones (eqs 19 and 20). ... [Pg.116]

Addition to Carbonyl Compounds. (TMSM)2Zn can be used for the preparation of a wide range of mixed organozinc compounds, in which the (trimethylsilyl)methyl (TMSM) moiety acts as a non-transferable group.As a result only a slight excess of the mixed zinc reagent is required in the reaction with aldehydes, a process which affords secondary alcohols in good yields (eq... [Pg.77]
