Arylalkynes can be converted into α-diketones with the use of a copper catalyst, and also be transformed into vinyl acetates under metal-free conditions, both in the presence of PhI(OAc)2 as an oxidant at room temperature. A series of substituted α-diketones were prepared in moderate to good yields. A variety of vinyl halides could be regio- and stereo-selectively synthesized under mild conditions, and I, Br and Cl could be all easily embedded into the alkynes. This journal is
Synthesis of 2-functionalized 1-chloro-1-iodo-1-alkenes from 1-chloro-1-alkynes and IPy2BF4

1-Chloro-1-alkynes react with bis(pyridine)iodine(I)tetrafluoroborate (1) and nucleophiles (AcOH, HCOOH, Cl, Br, I) to give, in a regio- and stereoselective addition, 2-functionalized 1-chloro-1-iodo-1-alkenes.
