title: Rhodium-catalyzed borylative cyclization of 2-alkynylaryl isocyanates with bis(pinacolato)diboron.
abstract: 2-alkynylaryl isocyanates reacted with bis(pinacolato)diboron in the presence of a cationic rhodium(I) 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.
