The cross-coupling reaction of vinylindiums generated via hydroindation of terminal alkynes with diaryliodoniums salts

In InCl3–NaBH4–MeCN system, vinylindiums generated by hydroindation of aryl terminal alkynes can undergo cross-coupling reaction with diaryliodonium salts high regio- and stereoselectively. But under the same conditions, the aliphatic terminal alkynes do not react very well.
