Cu(I)-catalyzed coupling of lactams with (E)-2-chlorovinyliodides or (E)-2-bromovinyliodides produces the corresponding β-haloenamides in moderate to excellent yields.

An efficient simple method was developed to prepare hetero E-1,2-dihaloolefins from mono- or disubstituted alkynes, in which, NXS (X = Br, I) was utilized as the electrophilic reagents and aqueous hydrohalic acid as the nucleophile. Moreover, Z-type dihalogenation olefins could be obtained from the terminal silylacetylene.

Alkynes react with bis(pyridine)iodonium (I) tetrafluoroborate (1) and nucleophiles (CH3COOH, HCOOH, Cl-, pyridine, Br-, I-) to give 1,2 iodofunctionalized alkenes.The regiochemistry of the processes is in accordance with
ORGANIC SYNTHESIS USING HALOBORATION REACTION VIII. STEREO- AND REGIOSELECTIVE SYNTHESIS OF -1,2-DIHALO-1-ALKENES

, p. 1065 - 1068 (2007/10/02)
-1,2-Dihalo-1-alkenes can be prepared stereo- and regioselectively in good yields from 1-alkynes by the bromoboration with tribromoborane, followed by the treatment with iodine chloride or bromine chloride in the presence of sodium acetate.
