PROCESS FOR PREPARING 2,2-DIBROMOMALONAMIDE

-

Page/Page column 5, (2011/06/19)

The present invention generally relates to a process for preparing 2,2-dibromomalonamide from 2,2-dibromo-3-cyanoacetamide.

Conversion of nucleophilic halides to electrophilic halides: Efficient and selective halogenation of azinones, amides, and carbonyl compounds using metal halide/lead tetraacetate

Kim, Jeum-Jong,Kweon, Deok-Heon,Cho, Su-Dong,Kim, Ho-Kyun,Lee, Sang-Gyeong,Yoon, Yong-Jin

, p. 194 - 200 (2007/10/03)

AlCl3/Pb(OAc)4 and ZnBr2/Pb(OAc) 4 are efficient electrophilic N- and α-C-halogenating agents. A variety of azinones, amides and carbonyl compounds were chemoselectively and regioselectively N-, or α-C-halogenated in good to excellent yield using AlCl3/Pb(OAc)4 and ZnBr2/Pb(OAc)4 in acetonitrile.
