摘要:
Essential additives: The addition of bis(1,3-butadienyl) compounds (tetraenes) was essential in the efficient Nicatalyzed cross-coupling of organozinc reagents with alkyl bromides and a tosylate (see scheme, X = C(CO2Me)2 or NCH2Ph). The efficiency of the Ni-catalyzed cross-coupling of an alkyl fluoride with a Grignard reagent was also improved by using these tetraenes.
