One-pot synthesis of bromodifluoroacetimidoyl halides and its Suzuki coupling reactions with aryl boronic acids

Wu, Yong-Ming,Li, Ya,Deng, Juan

, p. 791 - 795 (2005)

N-aryl bromodifluoroacetimidoyl halides were prepared by the reaction of bromodifluoroacetic acid, triphenyl phosphine, p-arylaniline and triethylamine in tetrachloromethane in good yields. Palladium-catalyzed cross-coupling reaction of N-aryl bromodifluoroimidoyl iodide with arylboronic acids was realized to afford bromodifuoromethyl ketimine in good yields.
