2-Alkynylaryl isocyanates reacted with bis(pinacolato)diboron in the presence of a cationic rhodium(l) catalyst to produce borylated 3-alkylideneoxindoles stereoselectively. The carbon-boron linkage formed was further transformed via reactions such as a cross-coupling and a halogenation reaction. American Chemical society.
